From the standard, the international inch, 25.4 mm exactly
The math
- A fraction is its top number divided by its bottom number: 37/64 in = 37 ÷ 64 = 0.578125 in.
- An inch is exactly 25.4 mm, so 0.578125 × 25.4 = 14.684375 mm, or 14.684 mm to three places.
- In feet, divide by 12: 0.578125 ÷ 12 = 0.048177 ft. In centimetres, divide the mm by 10: 1.4684375 cm.

A tape or rule marked more coarsely than 64ths can’t show 37/64 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 | 5/8 in | +0.046875 | +1.191 |
| 1/16 | 9/16 in | −0.015625 | −0.397 |
| 1/32 | 19/32 in | +0.015625 | +0.397 |
