From the standard, the international inch, 25.4 mm exactly
The math
- A fraction is its top number divided by its bottom number: 29/32 in = 29 ÷ 32 = 0.90625 in.
- An inch is exactly 25.4 mm, so 0.90625 × 25.4 = 23.01875 mm, or 23.019 mm to three places.
- In feet, divide by 12: 0.90625 ÷ 12 = 0.075521 ft. In centimetres, divide the mm by 10: 2.301875 cm.
- The same size in finer steps: 29/32 = 58/64. A tape marked in 16ths, 32nds or 64ths shows it at those marks.
29/32 to the nearest 1/8, 1/16
A tape or rule marked more coarsely than 32ths can’t show 29/32 exactly. The nearest marks, and how far off each is (plus means the mark is bigger; a size exactly halfway goes to the bigger mark):
| Nearest | Mark | Off by (in) | Off by (mm) |
|---|---|---|---|
| 1/8 | 7/8 in | −0.03125 | −0.794 |
| 1/16 | 15/16 in | +0.03125 | +0.794 |
