How the conversion works
- Split the decimal. Separate the whole-number part from the decimal part. 0.375 has no whole-number portion, so the full value carries 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. 0.375 × 16 = 6 exactly, with no rounding needed.
- Simplify. Reduce the fraction using the greatest common divisor of numerator and denominator. 6/16 shares a factor of 2, which simplifies to 3/8.
- Verify in mm. Multiply the decimal inches by 25.4 to confirm the metric value: 0.375 × 25.4 = 9.525 mm.
