What units are supported?

Length: mm, cm, m, km, in, ft, yd, mi. Weight: mg, g, kg, t, oz, lb. Temperature: °C, °F, K. Volume: mL, L, m³, gal, qt, pt, fl oz. Area: mm², cm², m², km², ha, in², ft², ac.

How accurate are the conversions?

All conversions use precise conversion factors defined by international standards. Results are displayed with up to 6 significant figures, which is sufficient for most practical applications.

Why is temperature conversion different?

Temperature scales have different zero points (Celsius: water freezing at 0°C, Fahrenheit: water freezing at 32°F, Kelvin: absolute zero at 0K). This requires offset calculations in addition to ratio conversions.

Can I convert between metric and imperial units?

Yes. The tool supports both metric (SI) units and imperial/US customary units. You can convert between any combination, such as meters to feet, kilograms to pounds, or liters to gallons.

Is my data sent to a server?

No. All calculations happen entirely in your browser using JavaScript. Your input values are never transmitted over the network. The tool works offline after the page loads.
