Fraction to Decimal Converter
Convert any fraction to its decimal equivalent instantly. Enter a numerator and denominator, and the calculator returns the decimal value. Some fractions produce terminating decimals (like 1/4 = 0.25), while others produce repeating decimals (like 1/3 = 0.333...). The calculator shows up to 10 decimal places for accuracy.

Fraction to decimal: frequently asked questions
How do I convert a fraction to a decimal?
Divide the numerator by the denominator. For example, 3/4 = 3 divided by 4 = 0.75. Some fractions produce repeating decimals: 1/3 = 0.333..., where the 3 repeats infinitely.
What is a repeating decimal?
A repeating decimal has digits that repeat infinitely. For example, 1/3 = 0.3333... (the 3 repeats). These are also called recurring decimals. The notation 0.3 with a bar over the 3 means the 3 repeats.
What are terminating decimals?
A terminating decimal ends after a finite number of digits. For example, 1/4 = 0.25. A fraction produces a terminating decimal if the denominator only has factors of 2 and 5.
Which fractions give repeating decimals?
Fractions whose denominators have prime factors other than 2 and 5 produce repeating decimals. For example, 1/3 (denominator 3) and 1/7 (denominator 7) both repeat, while 1/8 (denominator 2 cubed) terminates.
Why convert fractions to decimals?
Decimals are easier to compare, use in calculations, and display on modern devices. Fractions are more precise for certain applications and easier to understand in cooking and construction measurements.
