Convert between SI and historical plane-angle units (radian, milliradian, degree, gradian, turn, arcminute, arcsecond) anchored to the BIPM SI Brochure definition of the radian.
Convert between metric and imperial area units (square millimetre, square centimetre, square metre, hectare, square kilometre, square inch, square foot, square yard, acre, square mile) with NIST-grade exact factors, plus tsubo and jo for Japanese and Taiwanese property listings.
Find your starting bra size from two measurements, in EU, FR/ES, IT, UK, US or AU sizes, with sister sizes and the size a store chart would give.
Convert between bits, bytes, and every decimal (kB, MB, GB, TB) and binary (KiB, MiB, GiB, TiB) unit — with the KiB-vs-KB distinction done right.
Convert density between kg/m³, g/cm³, g/mL, kg/L, lb/ft³, lb/in³, oz per US gallon and slug/ft³. Every factor is exact by definition, derived from the SI meter and the 1959 international pound.
Convert between SI, electrical, and thermal energy units (joule, kilojoule, megajoule, watt-hour, kilowatt-hour, thermochemical calorie, IT calorie, kilocalorie, BTU, US therm, electronvolt) with NIST-grade exact factors anchored to the 2019 SI redefinition.
Konvertera mellan enheter för längd, massa, volym, area, temperatur, tryck, energi, effekt, kraft, vridmoment och vinkel med exakta NIST-faktorer.
Convert between SI, gravitational, and CGS force units (newton, kilonewton, dyne, kilogram-force, tonne-force, pound-force, ounce-force, short-ton-force) with NIST-grade exact factors anchored to CGPM 1901 standard gravity.
Convert between metric, imperial, and astronomical length units (millimetre, metre, kilometre, inch, foot, yard, mile, nautical mile, ångström, light-year, AU, parsec) with NIST-grade exact factors.
Convert mass between metric (kg, g, mg, tonne), avoirdupois (lb, oz, stone, short ton, long ton), troy ounce, grain, and the metric carat with NIST-grade exact factors.
Omvandla europeiska skostorlekar till brittiska direkt. Kompletta EU ↔ UK-tabeller för herr, dam och barn med fotlängd i cm och tum.
Convert between SI and historical power units (watt, kilowatt, megawatt, mechanical horsepower, metric horsepower / PS, electric horsepower, BTU per hour, kilocalorie per hour, foot-pound per second). Disambiguates the three horsepower variants that vary by about 10 W.
Convert between SI, atmospheric, and gravitational pressure units (pascal, kilopascal, megapascal, bar, millibar, atmosphere, torr, mmHg, psi, kgf/cm², inH2O, cmH2O) with NIST-grade exact factors and conventional liquid-column values.
Convert shoe sizes between US and EU instantly. Quick reference charts for men's, women's, and kids' sizes with foot length in cm and inches.
Convert shoe sizes between US and UK instantly. Quick reference charts for men's, women's, and kids' sizes with foot length in cm and inches.
Convert speed between km/h, mph, m/s, knots, feet per second, Mach and the speed of light. Every factor is exact by definition except Mach, which is flagged as a reference condition.
Convert between Celsius, Fahrenheit, Kelvin, Rankine, and Réaumur temperatures. Handles non-multiplicative scales correctly using the SI offset definition (0 °C = 273.15 K exactly, 13th CGPM 1967).
Convert between metric, US customary, and UK imperial volume units (millilitre, cubic centimetre, litre, cubic metre, cubic inch, cubic foot, cubic yard, US fluid ounce, US pint, US gallon, UK pint, UK gallon) with NIST-grade exact factors.
