About this tool
This page opens the length converter set to inches → centimeters. Since 1959 the international inch is defined as exactly 2.54 centimeters, so the formula is simply centimeters = inches × 2.54 — no rounding involved until you choose to round.
Handy reference points: 1 inch = 2.54 cm, 12 inches (one foot) = 30.48 cm, and 36 inches (one yard) = 91.44 cm. A 55-inch TV has a 139.7 cm diagonal; a 27-inch monitor is 68.58 cm. A 32-inch waist works out to 81.3 cm.
People reach for this conversion when reading US product listings, checking screen sizes, translating sewing patterns or woodworking plans, and interpreting clothing sizes. Enter inches on the left to get centimeters, or type centimeters on the right to go backwards — the fields stay in sync.
Example. Entering 1 inch returns 25.4 millimeters, because the inch factor is the exact 0.0254 meter definition.
Limit. The unit list is only millimeters, centimeters, meters, kilometers, inches, feet, yards, and miles.
