Unit Converter Guide: Length, Weight and Temperature

Unit conversion is a small task that appears constantly in product specs, recipes, shipping, travel, schoolwork, engineering notes and international content. A reliable converter prevents manual mistakes.

Length conversions

Length units usually convert through meters. For example, 1 foot is 0.3048 meters and 1 mile is 1,609.344 meters. This makes it easy to convert between metric and imperial systems.

Weight conversions

Weight conversions commonly use grams as the base. 1 kilogram is 1,000 grams, 1 pound is 453.59237 grams and 1 ounce is 28.349523125 grams.

Temperature conversions

Temperature uses formulas instead of simple multiplication. Celsius to Fahrenheit is (C * 9/5) + 32. Fahrenheit to Celsius is (F - 32) * 5/9.

Best practices

  • Keep enough decimals for technical values.
  • Round user-facing values only after conversion.
  • Check whether a project expects metric or imperial units.
  • Use temperature formulas instead of ratio conversion.
