Unit Converter
Convert length, weight, and temperature units.
About this tool
Convert values within length, weight, or temperature using the appropriate category and units. Length and weight conversions use fixed scale factors through a shared base unit. Temperature requires an offset as well as a scale: °F = °C × 9/5 + 32, and K = °C + 273.15. Switching the source and destination reverses the calculation. A 5-kilometer run is about 3.11 miles, 10 kilograms is about 22.05 pounds, and 20°C is 68°F. These comparisons help when reading an overseas weather forecast, measuring furniture for a room, following fitness distances, checking baggage weight, or translating specifications between metric and imperial systems. Select Length, Weight, or Temperature before choosing units, then enter a numeric amount; the result updates automatically. Conversion precision may display more decimals than a real measurement supports, so round according to the ruler, scale, or source data. The tool converts compatible units only: it cannot turn weight into volume because ingredient density would be required. Kelvin is an absolute scale and should not be interpreted like a simple degree-size label.
How to use
Start with the "Length," "Weight," or "Temperature" tab.
Select a unit under "From" and type the amount in "Enter value."
Set the "To" unit; the converted amount appears without a separate calculate button.
