Is this unit converter free?

Yes. It is free with no sign-up. Ten categories — length, weight, temperature, volume, area, speed, time, data storage, pressure and energy — convert instantly in your browser.

Why is there no currency converter?

Exchange rates change every day, so a money conversion without live rates would be a guess dressed up as an answer. This tool deliberately excludes currency; use your bank or a live-rate service for money.

How accurate are the conversions?

They use established SI and NIST factors — 1 inch is exactly 2.54 cm and 1 pound is exactly 0.45359237 kg — and the formula is shown with every result. Results are rounded to sensible significant figures for everyday use.

Can I use these results for medical, engineering or aviation work?

No. These are everyday conversions for school, cooking, travel and shopping. For medical dosing, engineering sign-off, aviation or anything safety-critical, verify professionally with the proper instruments.

Is anything I type uploaded or stored?

No. Every calculation happens in your browser tab. Nothing is uploaded, stored on a server or shared by this tool.
