Formula
Each unit converts through a base unit (metres, kilograms, litres, km/h, m² or kelvin): result = value × from-factor ÷ to-factor. Temperatures use offset formulas, e.g. °F = °C × 9/5 + 32.
Frequently asked questions
What units does this converter support?
Length (m, km, miles, feet, inches, nautical miles…), weight (kg, lb, oz, stone…), temperature (°C, °F, K, °R), volume (litres, US and imperial gallons, cups…), speed (km/h, mph, m/s, knots) and area (m², acres, hectares…).
How do I convert Celsius to Fahrenheit?
°F = °C × 9/5 + 32. So 100 °C = 212 °F and 0 °C = 32 °F.
Are US and imperial gallons the same?
No. A US gallon is 3.785 litres while an imperial (UK) gallon is 4.546 litres — about 20% larger. US cups, pints and fluid ounces are used here.
