When you need a unit converter

Students, travelers, cooks, and developers constantly switch between metric and imperial — or check FX for invoices. A single reliable converter saves time versus searching each category separately.

Common use cases

People search for unit converter online free when they need a fast result without installing software. Converting recipe volumes between cups and milliliters. Checking km/h vs mph for travel speed limits. Quick USD → INR estimates for freelance invoices.

wikawe handles these scenarios in seconds — open the tool, paste or upload, and copy the result. No account required.

Why browser-only processing matters

Many free online converters paste your code, images, or designs to a remote server. That is a poor fit for unpublished UI, API payloads, or personal photos.

wikawe utility tools run in your browser with JavaScript. Nothing is stored on our servers — open the tool, work locally, and copy or download the result.

Troubleshooting tips

If a result looks wrong, refresh and try a smaller sample first. Clear the field and paste again to rule out hidden characters.

Use an updated Chrome, Edge, Safari, or Firefox. For image tools, very large files may need more memory — close unused tabs first.

Pro tips

  • Use Swap to reverse From and To quickly.
  • Currency rates are cached about an hour in your session.
  • Temperature uses true °C / °F / K formulas — not linear factors.

Frequently asked questions

Does wikawe upload my data to a server?+

No. Formatting, conversion, and generation run in your browser. Your inputs stay on your device (currency rates use a short public rates request only).

Are currency rates live?+

They use European Central Bank reference rates (with a backup provider), updated roughly daily and cached locally for about an hour.

Do I need the internet for length or weight?+

No. Only Currency needs a short rates request.
