FAQ
How accurate are the conversions?
Conversions use precise conversion factors (e.g. 1 inch = 2.54 cm exactly). Results are displayed with up to 10 significant digits.
Why are temperature conversions different?
Temperature is not a ratio scale — converting between Celsius, Fahrenheit, and Kelvin requires formulas, not just multiplication. The converter uses the exact formulas for all three combinations.
Can I use this on mobile?
Yes. The tool is fully responsive and works on phones, tablets, and desktops.
Which unit systems are covered?
The converter covers SI (metric) units, imperial/US customary units, and some specialty units like knots for speed and acres for area.
