FAQ
Frequently Asked Questions.
Multiply the decimal by a power of 10 to eliminate the decimal point, then place that number over the corresponding power of 10. For example, 0.75 becomes 75/100. Finally, simplify by dividing both the numerator and denominator by their greatest common divisor (GCD) — 75/100 simplifies to 3/4.
0.375 as a fraction is 3/8. To get there: 0.375 = 375/1000. The GCD of 375 and 1000 is 125, so dividing both by 125 gives 3/8.
The detector analyzes digit sequences after the decimal point to identify repeating patterns. It checks for cycles of increasing length (1 digit, 2 digits, etc.) and verifies the pattern repeats consistently. Once found, it expresses the repeating portion using the standard algebraic method — for example, 0.333... becomes 1/3.
A mixed number combines a whole number with a proper fraction. For example, 1.75 as a mixed number is 1 3/4 — the whole-number part is 1 and the fractional remainder is 3/4. Mixed numbers are often easier to visualize than improper fractions like 7/4.
The tape measure feature displays your converted fraction on a visual ruler, making it easy for carpenters and woodworkers to see exactly where a measurement falls. Enter a decimal measurement (in inches) and the tool highlights the closest standard fraction on a 1/16" or 1/32" graduated tape.
The most common cooking fractions are 1/4, 1/3, 1/2, 2/3, and 3/4 — matching standard measuring cups and spoons. Less common but still used: 1/8 (half of 1/4 cup) and 1/16 (a tablespoon in a cup). Cooking mode rounds your result to the nearest practical kitchen fraction.
Yes. The calculator preserves the negative sign throughout the conversion. For example, -0.625 converts to -5/8. The magnitude is converted the same way as a positive decimal, and the negative sign is simply carried along.
Nearest fraction rounds your exact decimal to the closest fraction with a denominator you choose (such as eighths, sixteenths, or thirty-seconds). This is especially useful in construction and machining, where measurements must align to standard fractional increments. For example, 0.3 rounded to the nearest 1/8 is 2/8 (or 1/4), and to the nearest 1/16 is 5/16.
