What unit categories are supported?

Length, Weight/Mass, Volume, Area, Speed, Temperature, Data Storage, Energy, Pressure, Frequency, Fuel Economy, and Plane Angle. We're adding more categories regularly.

How many significant figures are used in conversions?

Conversions are calculated with up to 10 significant figures for precision. The display rounds to 6 significant figures for readability, but the full precision is used in calculations.

Can I convert in both directions simultaneously?

Yes. Our converter shows the conversion in both directions at once (e.g., 10 meters = 32.808 feet, AND 10 feet = 3.048 meters).

How do I convert meters to feet?

1 meter = 3.28084 feet. Multiply meters by 3.28084 to get feet. Or just use our converter: enter your value in meters, select meters → feet, and get the instant result.

What is the difference between a US gallon and a UK gallon?

They're different! 1 US gallon = 3.785 liters. 1 UK (Imperial) gallon = 4.546 liters. Our converter supports both — make sure to select the correct gallon type.
