Answer
7/8 in
0.875 in = 7/8 in (1/64 in) = 22.225 mm

0.875 inches equals 7/8 inch, a standard bolt, wrench, and pipe fitting size found throughout structural and plumbing hardware. It is also a common step on fractional drill bit index sets used for larger clearance holes. Sitting exactly between 13/16 in (0.8125 in) and 15/16 in (0.9375 in), it reads as 7/8 in whether you round to 1/16, 1/32, or 1/64 precision.

How the conversion works

  1. Split the decimal. Separate the whole-number part from the decimal part. 0.875 has no whole-number portion, so the full value converts into the fraction.
  2. Multiply by precision. Multiply the decimal by the denominator you want, 16, 32, or 64, then round to the nearest whole number. 0.875 × 16 = 14 exactly, with no rounding needed.
  3. Simplify. Reduce the fraction using the greatest common divisor of numerator and denominator. 14/16 shares a factor of 2, which simplifies to 7/8.
  4. Verify in mm. Multiply the decimal inches by 25.4 to confirm the metric value: 0.875 × 25.4 = 22.225 mm.
