Frequently asked questions.

What is the difference between metric and imperial units?
Metric units (meters, centimeters) are based on powers of ten and used worldwide. Imperial units (feet, inches, miles) are primarily used in the US and UK.
How do I convert height from feet and inches to centimeters?
Enter your height as feet and inches (e.g., 5ft 10in) in the input, select feet as the source unit, and choose centimeters as the target.
What is a mil or thou?
A mil (also called a thou) is one thousandth of an inch (0.0254 mm), commonly used in manufacturing tolerances.
Can I display results as fractions?
Yes. Enable fraction output and choose a precision like 1/16 or 1/64 for tape-measure style results.
