Unit Converter

This tool supports eight categories of units: Length (mm, cm, m, km, inch, foot, yard, mile), Weight (mg, g, kg, lb, oz, ton), Temperature (Celsius, Fahrenheit, Kelvin), Volume (ml, l, gallon, cup, tbsp, tsp, fl oz), Area (sq m, sq km, sq ft, sq mi, acre, hectare), Speed (m/s, km/h, mph, knots), Time (ms, sec, min, hour, day, week, month, year), and Data Storage (bit, byte, KB, MB, GB, TB, PB).

Simply type a value into any unit field and all other fields in the same category update instantly. There is no need to select source and target units separately — every field is both an input and an output.

Binary units use a factor of 1024 (e.g., 1 KB = 1024 bytes), which is standard in operating systems and memory. Decimal units use a factor of 1000 (e.g., 1 KB = 1000 bytes), commonly used by storage manufacturers. You can toggle between both modes in the Data Storage tab.

All conversions use precise mathematical formulas with floating-point arithmetic. Results are displayed with up to six significant decimal places, which is sufficient for everyday and professional use.
