How to convert 5 cm to inches

inches = cm ÷ 2.54
5 ÷ 2.54 = 1.968504 in

The inch has been defined as exactly 2.54 cm since 1959, so dividing by 2.54 is exact; the long decimal is just what that division produces. Multiplying by 0.3937 gives the same answer to four places.

Quick estimate

Multiply by 4 and divide by 10: 5 × 0.4 = 2 in. That overshoots by 0.03 in (about 1.6%) — fine for a rough check.

Things about 5 cm long

  • About the same as the length of an AA battery, 5.05 cm (1.99 in).
  • 7% shorter than the short side of a credit card, 5.4 cm (2.13 in).
  • 17% longer than the minimum diameter of a golf ball, 4.27 cm (1.68 in).
  • Hardware and crafts. US bolts, drill bits and beads are sized in fractions of an inch, so 5 cm is shopped as roughly 1 15/16 in (50 mm on metric parts).
