OpenExact definitions, not rounded estimates
The pound, international mile, US gallon and square foot each have a fixed definition. Conversions use those definitions, so a displayed answer is limited only by how many decimals you choose to show.
The direction matters
Multiply to go one way and divide to go the other. Each page states the factor in both directions so you can see which operation applies to the number you have.
Categories keep unlike units apart
Mass, volume, area, speed and temperature each convert on their own terms. Temperature uses an offset as well as a scale; area needs the length factor squared.
Common questions
What is the most common conversion mistake?
Applying a length factor to an area or volume. Square units need the factor squared and cubic units need it cubed.
Why do US and Imperial gallons differ?
They are separate definitions. One US liquid gallon is about 3.785 litres, while one Imperial gallon is about 4.546 litres.
