📝 About Unit Converter
The Unit Converter switches values between common metric and imperial units in three categories: length, weight and temperature. Pick a category, enter a value, choose the “from” and “to” units, and the converted result appears immediately.
Length covers millimeters, centimeters, meters, kilometers, inches, feet and miles. Weight covers milligrams, grams, kilograms, metric tonnes, ounces and pounds. Temperature converts between Celsius, Fahrenheit and Kelvin. It is useful for reading overseas recipes, comparing product sizes from international stores, checking a running distance in miles, or understanding a weather forecast in Fahrenheit.
Length and weight are converted through a base unit (meters or grams) using standard factors, such as 1 inch = 2.54 cm, 1 foot = 0.3048 m, 1 mile = 1,609.344 m and 1 pound ≈ 453.592 g. Temperature uses formulas rather than a single factor: °F = °C × 9/5 + 32 and K = °C + 273.15. Results are rounded to six decimal places, which is more than enough precision for everyday use.
