Common Converters

Common converters handle the everyday conversions people search for most, each on its own page with the exact factor, a chart and a worked example. Popular pairs include cm to inches, kg to lbs, Celsius to Fahrenheit, miles to km and cups to mL, and each has a matching reverse page.

For more units in one place, the general converters cover length, weight, volume, temperature, area, pressure, energy, power, force, time, speed, angles, fuel consumption, dry volume and data storage. The height converter shows centimeters as feet and inches, the number base converter switches between binary, decimal, octal and hex, and the case converter changes text between upper, lower, title and sentence case.

Factors follow the exact definitions, such as 1 inch = 2.54 cm and 1 pound = 0.45359237 kg. Watch for unit pairs that differ by region: US and imperial gallons, cups and miles per gallon are not the same size.
