Unified unit converter — Length, Weight, Temperature, Volume, Area, Speed, Time, Power
This all-in-one conversion calculator handles Length, Weight, Temperature, Volume, Area, Speed, Time, and Power units in a single interface. Simply select the category, enter your value, choose the source and target units, and click Convert. It uses meters, kilograms, Kelvin, cubic meters, square meters, meters per second, seconds, and watts as base units for consistency.
Length (mm, cm, m, km, in, ft, yd, mi, nmi), Weight (mg, g, kg, oz, lb, ton, tonne), Temperature (C, F, K), Volume (mL, L, gal, qt, pt, cup, fl oz, m³), Area (mm², cm², m², ha, km², in², ft², ac, mi²), Speed (m/s, km/h, mph, ft/s, kn), Time (ms, s, min, h, day, week, month, year), and Power (W, kW, MW, hp, BTU/h).
Temperature conversions use offset formulas (e.g., °F to °C: (°F − 32) × 5/9) rather than simple multiplication, because temperature scales have different zero points. The calculator handles these offsets automatically for Celsius, Fahrenheit, and Kelvin.
