Frequently Asked Questions
Which unit categories are supported?
Length, weight, temperature, volume, area, speed, time, and data storage, with both metric and imperial units throughout. Switch categories from the selector in the workspace.
How is temperature converted?
Temperature uses formulas rather than simple multiplication, because the zero points differ. The converter applies °F = °C × 9/5 + 32 and K = °C + 273.15 correctly in every direction.
Can I convert metric to imperial?
Yes. Metric and imperial units are available side by side in every category — for example metres to feet, kilograms to pounds, or litres to gallons.
Are the conversion factors accurate?
Yes. The converter uses standard internationally agreed factors and runs with full floating-point precision in your browser.
