Inches to Centimeters Converter
This inch to centimeter converter changes any length in inches into centimeters. The page loads in length mode with inch as the source unit and centimeter as the target, so typing a measurement immediately shows the metric equivalent: 1 in = 2.54 cm, 12 in = 30.48 cm, and 70 in is about 177.8 cm. It is useful for TV and monitor diagonals, pipe sizes, lumber, and any product listing that specifies inches when you think in metric. The swap button reverses the direction if you need cm to inches instead. All calculations run locally in JavaScript, so nothing is sent to a server or saved. Copy the result or use it to compare sizes at a glance.
