Frequently Asked Questions
Everything you need to know about decimal conversions, accuracy, and formulas.
01How do you convert decimal inches to fractional inches?▼
To convert decimal inches to fractions: 1) Multiply the fractional part of the decimal by your desired denominator (such as 16, 32, or 64). 2) Round to the nearest whole number to get the numerator. 3) Reduce the resulting fraction (e.g. 12/16 reduces to 3/4) and combine with the whole inches.
02How many millimeters are in an inch?▼
By international agreement, exactly 1 inch = 25.4 millimeters (2.54 centimeters). To convert decimal inches to millimeters, simply multiply the inches value by 25.4.
03What is a 'thou' or 'mil' in engineering measurements?▼
A thou (thousandth of an inch, or mil) equals 0.001 inches (0.0254 mm). It is the standard precision measurement unit used in machining, PCB manufacturing, and mechanical engineering.
