Free online unit converter with 25+ categories: length, mass, temperature, time, area, volume, speed, energy and more. Live conversion as you type.
CalcGlobe's universal unit converter handles 60+ measurement categories — length, mass, temperature, area, volume, speed, time, pressure, energy, power, force, data storage, frequency, angle, fuel economy, typography, and many specialised engineering, electrical, chemistry, and medical unit families.
Measurement categories support conversion between the listed units and a reference table. Currency rates come primarily from ExchangeRate-API, with Frankfurter / ECB as a fallback. Available currencies depend on the responding provider.
Inputs: Convert 5 kilometres to other length units
Accuracy depends on the definition, stored factor and rounding for the selected unit. Currency rates are reference values from the responding provider; they exclude transaction fees and do not guarantee the rate offered by a bank or exchange service.
Yes — the calculator supports every common metric/imperial pair: km/miles, kg/pounds, °C/°F, litres/gallons (US and UK), Pa/PSI, joules/BTU, and many more. For temperature, conversions use the correct formula (not a simple ratio) because the scales have different zero points.
