How this works in your browser
A decimal is converted by treating its digits as a fraction over the appropriate power of ten, then reducing using the Euclidean algorithm to find and divide out the greatest common divisor. That reduction is what turns 4375 over 10000 into seven sixteenths in a single step rather than through repeated halving. The limitation worth understanding is inherent to finite decimals: any decimal you can type is a rational number over a power of ten, so a repeating value such as a third can only ever be approximated by however many digits you enter. Values above one are split into a whole part and a remainder, which is how measurements are actually read aloud.

Frequently asked questions
How are fractions simplified?
The greatest common divisor of the numerator and denominator is found and divided out, so the fraction is always shown in its lowest terms.
What about repeating decimals?
Repeating decimals are approximated based on their visible digits - more decimal places give a closer approximation.
Are mixed numbers supported?
Yes, decimals greater than 1 are shown as a mixed number (whole number plus fraction), matching how measurements are typically read.
Why does 0.333 not give exactly one third?
Because a third has no exact decimal representation; the digits repeat forever. Given a finite decimal the conversion produces the fraction that decimal genuinely equals, which is 333 over 1000. Entering more threes moves the result closer to a third without ever reaching it.
How do I convert to sixteenths for woodworking?
Read the fraction produced and scale it to the denominator your tape uses. A decimal of 0.4375 simplifies to seven sixteenths exactly, which is why imperial measurements convert cleanly when they originated as fractions in the first place.
Why do some decimals give an ugly fraction?
Because they were never a simple fraction to begin with. A measurement of 0.37 inches is 37 hundredths, which does not reduce, and no amount of simplification will make it tidy. Rounding to the nearest useful fraction of an inch first is usually what you actually want.
Is anything I enter transmitted?
No. The conversion runs entirely in your browser.
