Quickly find the decimal equivalent for any inch fraction
Locate the fraction you are working with (e.g., 3/8") in the left column. The chart is sorted by size.
Look across to the Decimal column to find the precise decimal equivalent (e.g., 0.375").
If enabled, use the Millimeters column to find the metric equivalent for international projects.
Most standard tape measures are divided into 16ths. Understanding the lengths of the markings is the key to reading them quickly:
Count the "ticks" from the inch mark:
• 2 ticks = 2/16 = 1/8"
• 4 ticks = 4/16 = 1/4"
• 8 ticks = 8/16 = 1/2"
• 12 ticks = 12/16 = 3/4"
Essential for precision work in various trades
Convert blueprint fractions to decimal inputs for lathes, mills, and CNC machines. Essential for maintaining tolerances.
Translate tape measure readings (fractions) to digital plan dimensions (decimals) for precise cuts and joinery.
Perfect for home projects where you need to match hardware sizes or drill bits to material thicknesses.
Inch fractions are based on repeatedly halving the inch. We start with 1 inch, cut it in half to get 1/2". Cut that in half to get 1/4", then 1/8", 1/16", 1/32", and finally 1/64". Machinists often work in "thous" (thousandths of an inch), where 0.001" is one thou.

1/32 inch is equal to 0.03125 inches. In most workshop settings, this is rounded to 0.031".
31 / 64 = 0.484375
5/16 inch is exactly 0.3125 inches. This is a very common fastener and drill bit size.
1/16 inch is equal to 0.0625 inches. This is the smallest division on many standard measuring tapes.
Many measuring tools like tape measures use fractions (1/4", 1/8"), but digital calipers, CNC machines, and CAD software often require decimal inputs (0.25, 0.125). A conversion chart bridges this gap without needing a calculator.
