Measurement conversion questions

Can I enter a height in feet and inches?

Yes. The height converter accepts feet and inches or centimeters. It normalizes inches into feet and reports the equivalent centimeters.

How do exact conversions differ from rounded results?

An exact factor defines the relationship between units, such as 1 inch = 25.4 mm. The converter rounds displayed decimals for readability. The fractional inches converter labels a nearest fraction as approximate when rounding changes the value.

Why do bit and byte rate symbols use different capitalization?

Lowercase b means bit and uppercase B means byte. One byte is eight bits, so 100 Mbps converts to 12.5 MB/s using decimal prefixes.

Does the flow converter treat U.S. and imperial gallons as equal?

No. One U.S. gallon is 3.785411784 liters; one imperial gallon is 4.54609 liters. Select the matching gallon unit for your measurement.

How do I enter a pace with seconds?

Enter minutes and seconds as mm:ss, such as 5:00 for five minutes per kilometer or mile. Seconds must range from 00 through 59.

Do I need an account to use a converter?

Enter a value to see the result without an account. Each page also lists its formula, example, and unit sources.
