Unit Converter
Free unit converter for length, weight, volume and temperature. Useful for quotes, shipping and product invoices.
How the unit converter works
Pick a category, enter a value and choose the units to convert between.
Formula
Each value is converted to a base unit (metre, kilogram, litre) and then to the target unit. Temperature uses its own formulas, such as °F = °C × 9/5 + 32.
Worked example
Example: 5 miles = 8.047 kilometres; 70°F = 21.1°C.
FAQ
