How the conversion works
- Split the decimal. Separate the whole-number part from the decimal part. 0.5625 has no whole-number portion, so the entire value converts into the fraction.
- Multiply by precision. Multiply the decimal by the denominator you want, 16, 32, or 64, then round to the nearest whole number. 0.5625 × 16 = 9 exactly, with nothing to round off.
- Simplify. Reduce the fraction using the greatest common divisor of numerator and denominator. 9 and 16 share no common factor, so 9/16 is already in lowest terms.
- Verify in mm. Multiply the decimal inches by 25.4 to confirm the metric value: 0.5625 × 25.4 = 14.2875 mm.
