Measurement Converter
Convert length, area, volume and weight between metric, imperial and US units.
How to use the Measurement Converter
Choose Length, Area, Volume or Weight, enter a value, then select the source and destination units. The result updates automatically.
How it works
The measurement converter covers length, area, volume and weight. Each value is converted through a consistent base unit, allowing metric, imperial and US customary units to be compared without manually remembering conversion factors.
Example: One metre is approximately 3.28084 feet. One UK gallon is 4.54609 litres, while one US gallon is approximately 3.78541 litres—so selecting the correct gallon matters.
What to keep in mind
Results are rounded for readable display. US and imperial volume units are not always identical, and “ton” can mean a metric tonne, US short ton or UK long ton. Choose the precise unit shown in the list.
Frequently asked questions
Why are there separate UK and US gallons?
They represent different volumes. A UK gallon is larger than a US liquid gallon.
Can I use decimal quantities?
Yes. Enter decimals for both small measurements and precise conversions.
