Unit Conversion Reference
CalcSolver's unit converter handles length, weight, temperature, volume, area, speed, and data storage conversions — covering the most commonly needed unit translations in everyday life, science, and engineering.
Key conversions: 1 mile = 1.609 km, 1 pound = 0.4536 kg, °F to °C: (F−32) × 5/9, 1 gallon = 3.785 liters. Temperature is unique because it uses offset conversion (not just multiplication), making Fahrenheit-Celsius conversion a common source of errors.
The metric system (used by 95% of the world) is based on powers of 10, making conversions within it straightforward. Converting between metric and imperial requires remembering specific conversion factors. For cooking, use volume conversions; for fitness, use weight/length conversions. See CalcSolver's fuel economy calculator for distance-volume combined calculations.
