3/8 inch is approximately equal to how many millimeters?

Explanation:
Converting inches to millimeters uses the standard factor 1 inch = 25.4 mm. For 3/8 of an inch, you multiply 25.4 by 3/8: 25.4 × 3/8 = 76.2 ÷ 8 = 9.525 mm. That’s about 9.5 mm, which rounds to 10 mm. So the closest approximation is 10 millimeters. The other options are noticeably farther away (5 mm is too small, 15 mm and 20 mm are too large).
