About Torque Converter
Torque Converter is a self-contained calculation workspace. Nm ft-lb kgf-m. Open the page, get the result, close the tab — that is the entire workflow.
Reach for Torque Converter when you need a predictable result on a single file. The page works on the first visit, the controls are visible without a menu, and the output is delivered the moment the engine finishes.
Torque Converter is a static page plus a client-side engine. The browser does the work; there is no separate backend in the loop for the actual processing. That architecture is why the tool starts immediately, why it does not depend on the load on a remote service, and why running multiple jobs in a row does not slow it down.
Behind the controls you see, standard browser APIs is doing the actual calculation. Formats are detected on load and the engine produces a deterministic output for any given input + options combination — useful when you need to re-run a job and expect identical results.
The hard constraints are easy to remember. Maximum input: 0 MB. Multiple files per run: no — one input at a time, by design, to keep results predictable. The same controls apply on every run.
Anyone who works with calculation on a casual basis — parents helping with maths, hobbyists planning DIY projects, finance teams modelling scenarios — finds Torque Converter a quick way to get the result. The page loads in under a second, the controls are visible from a single screen, and the result downloads or copies in one click.
The output handed back by Torque Converter is the output file. If you would prefer to keep the result in the browser instead of downloading it, you can copy it from the result panel and paste it directly into another tab — useful when the next tool in your workflow expects pasted text rather than a file.
Once you have used Torque Converter, the natural next steps depend on what you are doing with the result. Common follow-ups include Angle Converter, Density Converter, and Force Converter. These are surfaced on the page so you do not have to hunt the catalog manually.
Torque Converter is built around steady iteration on a small set of options rather than feature creep. Every additional setting attracts a slightly different audience, but a long settings panel makes the common case slower for everyone. The current controls reflect what users of the tool actually use.
Some context on why Torque Converter exists in this form: modern File APIs, high-performance JavaScript engines, and well-maintained open-source libraries now make it possible to perform calculation work entirely in the browser. Torque Converter is built on top of that capability, which is why a single page can host the full pipeline.
Torque Converter produces deterministic output: the same input plus the same options always produces the same result. That predictability matters when the result has to match an upstream specification or be reproducible later.
Pro tip: Torque Converter works just as well in a private/incognito window as in a normal one, which is occasionally useful when you want zero browser-history footprint of the job. Another tip: if the tool ever feels slow, it is almost always because the browser tab is competing for CPU with another tab — pausing or closing the heavy ones gives the engine room to work.
If Torque Converter appears to hang, the engine is almost certainly still working — large inputs simply take longer to process inside a browser than they would on a server with multi-core scheduling. For inputs near the 0 MB cap, give it up to a minute on a typical laptop before assuming something is stuck.
Open the workspace above to start using Torque Converter. The engine loads on the first interaction so the page itself stays light, and once the tool is warm it processes subsequent jobs quickly. The moment the page is interactive, the tool is ready to do real work on your file.
How it works
- 1Open the Torque Converter workspace above. The interface is a single page, so there is nothing to navigate.
- 2Add your calculator input by dropping it onto the page or browsing for it.
- 3Tweak the controls if the defaults are not quite right for your input. The options are kept short and labelled in plain language.
- 4Trigger processing. standard browser APIs reads your input, applies the transformation, and writes the result back into the page.
- 5Grab the output as soon as the run completes. You can also copy the result instead of downloading if the next tool in your workflow accepts pasted input.
- 6Repeat the process for additional inputs whenever you need to. The page stays loaded, so subsequent runs are quick.
Common use cases
- Plan a project budget on a phone in a meeting using Torque Converter.
- Convert a foreign currency amount into your local one.
- Split a restaurant bill cleanly between a group.
- Confirm a unit conversion before quoting it in a report.
- Work out a percentage change between two figures.
- Estimate a finance schedule before approaching a bank.
- Forecast a fitness target without a paid app.
- Compare two scenarios side by side without spinning up a spreadsheet.
FAQ
How do I use the Torque Converter?
Enter a number followed by a unit token as shown in the placeholder, then read the multi-line equivalents.
Is this bidirectional?
Yes — toggle direction when available; both ways parse the same value plus unit pattern.
Are shoe or clothing sizes exact?
No — tables are approximate; brands differ so always verify with the manufacturer chart.
Is data uploaded?
No — unit math stays in your browser.
Why do conversions look long?
Scientific notation and many decimals show full precision you can round yourself for display.
Can I use commas in numbers?
Use plain decimal numbers without thousands separators for best parsing.
Why is my browser prompting me when I open Torque Converter?
Torque Converter only needs the standard web platform — file picker access for the inputs you choose to load, and optionally clipboard access if you copy the result rather than downloading it. There is no microphone, camera, geolocation or background-permission request, because none of those are needed for the work the tool does.
Are there any restrictions on using Torque Converter at work?
Torque Converter can be used for personal and commercial work alike — there is no separate "business" licence to purchase. The output you generate is yours to use however you want, including in client deliverables, internal documents, or commercial products. Favtoo's only ask is fair, individual use; the tool is not designed to be embedded as a backend service or wrapped behind an API for resale.
How accurate is Torque Converter?
Torque Converter is built on standard browser APIs, which is the same class of engine used by professional calculation pipelines. For deterministic operations, the output is byte-identical to what an equivalent CLI run would produce; for operations involving a codec or a model, the result is well within the range of what comparable tools generate. If you have a specific reference output you need to match, run a small test job first to confirm the configuration produces what you expect.
Is Torque Converter keyboard accessible?
Torque Converter uses native HTML controls wherever possible, which means keyboard navigation, focus rings, and screen-reader labels work the way the platform expects. The drop zone accepts files via the keyboard-accessible file picker as well as drag-and-drop, and result downloads use standard browser download flows. If you spot an accessibility gap, Favtoo treats it as a bug worth fixing.
Can Torque Converter run inside a corporate firewall?
Torque Converter is a static page running an open-source engine in your browser, so a typical corporate firewall does not get in the way as long as it allows JavaScript to load from Favtoo. For teams that need to host it themselves on an internal network, the underlying engine (standard browser APIs) is open-source and can be packaged into a private build with the same behaviour. Reach out via the Contact page if that is something you are exploring.
Does Torque Converter need an internet connection to run?
Once the page is loaded, Torque Converter can complete jobs without an active internet connection — the engine is bundled with the page, so there is no per-job network call. The initial page load does require a connection (to fetch the static assets), but after that you can disconnect entirely and the tool will still work. This is a side-effect of the local-first architecture, not a deliberate "offline mode" feature.
Is there a desktop version of Torque Converter?
No installation is needed. Torque Converter runs as a normal web page, with no browser extension, no native helper, and no separate desktop client to download. That is partly a privacy choice — extensions can request broad permissions, while a regular page is sandboxed by default — and partly a convenience one: you can use Torque Converter on any computer you have temporary access to without leaving anything installed on it.
Can I process multiple files at once with Torque Converter?
Torque Converter processes one input at a time by design — it keeps memory usage predictable on lower-end devices and makes results easier to verify. To handle a folder, run the tool once per file; the page stays loaded between runs and remembers your last-used settings, so the second run is essentially instant.
How do I know I am using the latest version of Torque Converter?
Torque Converter is updated whenever the underlying engine releases an improvement or a bug fix. Because the tool is delivered as a static page, every visit fetches the latest version automatically — there is no "version" to manage on your end. If a particular release ever changes default behaviour, the change is documented on Favtoo's changelog so you can confirm what shifted.
