Exactly 2.54 cm to the inch

The inch is defined as exactly 2.54 cm, so inches = cm ÷ 2.54 with nothing lost: 2.54 cm is 1 in and 25.4 cm is 10 in.

How to Convert CM to Inches

  1. 1

    Divide by 2.54

    Inches = cm ÷ 2.54. For 14.5 cm: 14.5 ÷ 2.54 = 5.71 in. (Multiplying by 0.3937 gives nearly the same answer.)

  2. 2

    Round to a mark on the tape

    US tapes are marked in sixteenths of an inch, so round the decimal to the nearest one: 5.71 in is about 5 11/16 in.

  3. 3

    Over 12 inches? Split off the feet

    Divide the inches by 12 for feet: 100 cm is 39.37 in, or 3 ft 3.4 in. For longer lengths, the CM to Feet converter does this in one step.

CM to Inches Questions

Divide the centimeters by 2.54. For example, 30 cm ÷ 2.54 = 11.81 in, about 11 13/16 in on a tape. To go the other way, multiply inches by 2.54.

12.5 cm is 4.92 in — about 4 15/16 in on a tape measure, or 125 mm.

2 cm is 0.787 in — about 13/16 in to the nearest sixteenth of an inch, or 20 mm.

14.5 cm is 5.71 in, about 5 11/16 in on a tape.

2.8 cm is 1.1 in, about 1⅛ in. Another value people ask about: 11.8 cm is 4.65 in (about 4⅝ in).

Yes. Since 1959 the inch has been defined as exactly 2.54 cm, so the cm to inches ratio is 1 ÷ 2.54 ≈ 0.3937. Dividing by 2.54 is exact; multiplying by 0.3937 is a close shortcut.

50 × 70 cm is 19.69 × 27.56 in, about 19⅝ × 27½ in to the nearest eighth. A 60 × 90 cm print (90 × 60 cm turned sideways) is 23.62 × 35.43 in.

13.12 cm is 5.17 in, about 5 3/16 in. Likewise 9.43 cm is 3.71 in, about 3 11/16 in. Divide by 2.54, or type the value into the converter above.
