Frequently asked questions
How accurate are the conversion results?
Conversions use exact factors, for example, 1 inch = 25.4 mm exactly per international agreement. Results are computed in JavaScript's 64-bit floating-point arithmetic, accurate to about 15 significant digits. Rounding is applied only in the display, not the calculation.
Which unit categories and systems are supported?
8 categories: length, weight, temperature, volume, area, speed, time, and digital storage. Both metric (SI) and imperial/US customary units are included, and you can freely convert between any two units across systems.
Why are temperature conversions handled differently from other units?
Most unit conversions use simple multiplication. Temperature requires both a scale factor and an offset because the zero points differ, 0°C is not the same physical temperature as 0°F. Celsius to Fahrenheit is (C × 9/5) + 32, not just multiplication, which is why temperature can't be treated the same way as length or weight.
Are conversion results updated in real time?
Yes. Results update instantly as you type, no submit button needed. All math runs in your browser with no round-trip to a server, so there is no latency regardless of your connection speed.
Can I convert between metric and imperial units?
Yes. For every category, you can freely convert between any two units, including across systems. Select your source unit, enter a value, and select your target unit. All cross-system conversions are handled automatically.
