Unit Conversion Guide
Unit conversion is the process of expressing a measurement in a different unit while maintaining the same quantity. The key is knowing the conversion factor — the ratio between two units.
Length: The metric system uses millimeters, centimeters, meters, and kilometers. The imperial system uses inches, feet, yards, and miles. Key conversions: 1 inch = 2.54 cm, 1 foot = 0.3048 m, 1 mile = 1.60934 km.
Weight: Metric uses milligrams, grams, and kilograms. Imperial uses ounces and pounds. Key conversions: 1 ounce = 28.3495 g, 1 pound = 0.453592 kg.
Temperature: Celsius, Fahrenheit, and Kelvin each have different zero points and scale sizes. C to F: multiply by 9/5 and add 32. C to K: add 273.15. F to C: subtract 32 and multiply by 5/9.
