Type a fraction, a mixed number like 3 5/8, or a whole calculation such as (3/8)+(1/16) — the decimal updates as you type, to 10 significant digits. Built for woodworking, machining, construction take-offs and homework alike.
5/8
5 ÷ 8
0.625
3 5/8
3 + (5 ÷ 8)
3.625
7/16
7 ÷ 16
0.4375
decimal = numerator ÷ denominator
mixed number: decimal = whole + (numerator ÷ denominator)
Repeating results (1/3, 1/6, 1/7…) are shown to 10 significant digits, which is more than enough for any shop tolerance.
Divide the numerator by the denominator. For 5/8, 5 ÷ 8 = 0.625. For a mixed number like 3 5/8, keep the whole number and add the divided part: 3 + 0.625 = 3.625.
5/8 = 0.625 exactly. In sixteenths it is 10/16, and in thirty-seconds 20/32.
A fraction terminates only when the denominator's prime factors are 2 and 5. 1/3 = 0.333… and 1/6 = 0.1666… repeat forever, so this page shows them to 10 significant digits.
Yes. The box runs a live math parser, so (3/8)+(1/16), 2*7/16 and 3 5/8 - 1/4 all give an answer as you type.
