Frequently Asked Questions (FAQ)
How do you convert a fraction to a decimal without a calculator?
Divide the numerator by the denominator using long division. For example, to convert 3/8: 8 goes into 3 zero times, add decimal → 30 ÷ 8 = 3 remainder 6, 60 ÷ 8 = 7 remainder 4, 40 ÷ 8 = 5 → 0.375.
What is 1/2 inch in decimal?
1/2 inch = 0.5 inches. This is one of the most common conversions for woodworking and construction.
What is 5/8 of an inch in decimal?
5/8 inch = 0.625 inches. This measurement is commonly used for plywood thickness and router bits.
How do you read a tape measure in decimals?
Most tape measures show fractions (1/16, 1/8, 1/4, 1/2). To read in decimals, convert each fraction mark: 1/16 = 0.0625, 1/8 = 0.125, 3/16 = 0.1875, 1/4 = 0.25, 5/16 = 0.3125, 3/8 = 0.375, 7/16 = 0.4375, 1/2 = 0.5, etc.
What is the most common fraction used in woodworking?
The most common fractions in woodworking are 1/2, 1/4, 1/8, 1/16, and 3/4 inches. For fine woodworking, 1/32 and 1/64 inch precision is sometimes used.
How do you scale a blueprint measurement?
Use the scale factor shown on the blueprint. For example, if the scale is 1/4" = 1', multiply the measured inches on the plan by 4 to get feet. Our scale calculator above does this automatically.
