FAQ
What units does this converter support?
Length (millimeters through miles), weight (milligrams through US tons), and temperature (Celsius, Fahrenheit, and Kelvin).
How accurate are the conversions?
All conversions use standard, internationally recognized conversion factors — the same ones used in scientific and engineering contexts, accurate to at least 6 decimal places.
Why does the table show every unit at once instead of just one result?
It's often more useful to see a value across several units at a glance — for example, seeing a length in both feet and meters at the same time — rather than converting one pair repeatedly.
Can I convert temperature the same way as length and weight?
Not quite — temperature scales don't share a simple multiplier the way length and weight units do, since they have different zero points. This tool uses the correct dedicated formulas for Celsius, Fahrenheit, and Kelvin conversions.
What are some common conversions people look up?
Meters to feet, kilometers to miles, kilograms to pounds, and Celsius to Fahrenheit are among the most frequently searched — see the quick reference table above.
Why is 0°C equal to 32°F instead of 0°F?
Celsius and Fahrenheit place their zero points differently — Celsius was defined so that 0° is water's freezing point, while Fahrenheit's zero point was set using a different historical reference, which is why the two scales don't line up at zero.
What's the difference between a US ton and a metric ton?
A US ton (also called a short ton) equals 907.18 kilograms, while a metric ton equals exactly 1,000 kilograms — so a metric ton is about 10% heavier than a US ton.
