Convert between metric and imperial units for length, weight, volume, area, speed, temperature, data and time with instant, accurate results.
The Unit Converter switches values between metric and imperial units across length, weight, volume, area, speed, temperature, digital storage, pressure, energy and time, with results updating instantly as you type. It replaces hunting for a specific conversion formula online with a single interface covering the most commonly needed categories in daily life, cooking, travel, construction and study.
Every conversion uses the official SI conversion factors with full floating-point precision, so results for common pairs like cm to inches, kg to lbs or Celsius to Fahrenheit are accurate to many decimal places, not rounded approximations. Selecting a category shows the relevant units for that measurement type, and switching the 'from' and 'to' units recalculates immediately without needing to press a separate convert button.
Length, weight, volume, area, speed, temperature, digital storage, pressure and energy are all included, avoiding the need for separate single-purpose converters.
Conversions use official SI factors with full precision, updating live as you type rather than requiring a submit action.
Reversing a conversion, such as switching from cm-to-inches to inches-to-cm, takes a single click instead of re-selecting both units.
Runs entirely as a browser calculation, making it equally usable on a phone during travel or a desktop while doing homework.
Length (mm to miles), weight and mass (mg to tons), volume (ml to gallons), area (sq m to acres), temperature (Celsius, Fahrenheit, Kelvin), speed, time, digital storage (bytes to terabytes), pressure and energy are all covered, each offering the units people actually search for rather than obscure scientific-only variants.
Conversions are calculated using standard SI definitions and double-precision arithmetic, so results for exact conversions like inches to centimetres are mathematically exact, while approximate historical units are converted using their internationally agreed modern definitions.
Unlike most units, temperature scales are not simple multiplicative conversions — Celsius to Fahrenheit involves both a multiplication and an offset, and Kelvin has no negative values. The tool handles this automatically so you never need to remember the formula.
Search engine unit converters typically only support one category at a time and require a fresh search per conversion type. This tool keeps all categories in one interface with instant swapping, which is faster when converting several related values in a row.
Length, weight and mass, volume, area, temperature, speed, time, digital storage, pressure and energy — each with the common metric and imperial units.
Conversions use the official SI factors and full double precision, so results are exact to well beyond the number of decimals shown.
