What is a unit converter? A unit converter changes a measurement from one unit into another. This one handles length, weight, and temperature between metric and imperial units.
For length and weight, each value is converted using a fixed factor relative to a base unit (metres for length, grams for weight) and then to the target unit. For example, 1 inch = 0.0254 metres and 1 pound = 453.59237 grams.
Temperature uses formulas, not a single factor: °F = °C × 9/5 + 32, °C = (°F − 32) × 5/9, and K = °C + 273.15.
Length (such as metres, kilometres, miles, feet, and inches), weight (such as grams, kilograms, pounds, and ounces), and temperature (Celsius, Fahrenheit, and Kelvin).
