Frequently Asked Questions
Which unit categories are supported?
Length, weight, temperature, volume, area, speed, time, data size and more — covering the units people actually use daily.
How accurate are the conversions?
Standard internationally-defined conversion factors are used at full floating-point precision, which exceeds the precision any physical measurement needs.
Does temperature conversion use a formula instead of a factor?
Yes — temperature uses offset formulas (like °F = °C × 9/5 + 32) rather than a simple multiplier, and the tool handles this correctly.
Can I use it offline?
Once the page has loaded, conversions keep working without a network connection.
