FAQ
Which units does the converter support?
It supports the most commonly used length, weight, and temperature units, including millimeters, yards, miles, pounds, ounces, Celsius, Fahrenheit, and Kelvin.
Why are temperature conversions calculated separately?
Temperature scales have different zero points, so they cannot be converted with a simple proportional factor like length or weight.
How precise are the results?
Results are displayed to a maximum of 10 decimal places, which is sufficient for most everyday and practical work.
