FAQ
How accurate are the results? Conversion factors follow SI and exact defined values (e.g. 1 inch = 0.0254 m exactly). Results are rounded to six significant digits.
Can I convert between metric and imperial? Yes. For example, you can convert miles to kilometers, pounds to kilograms, or gallons to liters directly.
Why is 32 F equal to 0 C? The Fahrenheit and Celsius scales use different zero points and different step sizes. The converter applies the exact formula: C = (F - 32) x 5/9.
