Convert centimeters to inches, feet, meters, millimeters, and 4 more units. Includes quick presets, feet-and-inches display, and everyday object size chart.
The centimeter (cm) is one of the most commonly used metric length units, perfect for measuring everyday objects from pencils to furniture. One centimeter equals 10 millimeters, 0.01 meters, or approximately 0.3937 inches. This multi-direction converter accepts input in seven different units and outputs results in centimeters, millimeters, inches, feet-and-inches, meters, yards, kilometers, and micrometers.
Preset buttons cover key reference points like 2.54 cm (exactly 1 inch), 30.48 cm (1 foot), and common human heights in centimeters. A visual size comparison shows how your value relates to everyday objects like coins, credit cards, and door heights.
Whether you are converting a European clothing measurement to US inches, sizing furniture from an international catalog, or working on a school metric conversion assignment, this centimeter converter provides instant, accurate results with a built-in conversion reference table. It is also useful for construction notes, product specs, and shipping forms where mixed-unit dimensions are common.
The centimeter sits at the intersection of metric and imperial systems — most international products list dimensions in cm, while US consumers think in inches and feet. This tool converts both ways and includes a feet-and-inches composite display, which is especially useful for height conversions, shopping decisions, and documentation checks.
1 cm = 10 mm = 0.3937 in = 0.03281 ft = 0.01 m Inches = cm ÷ 2.54 Feet = cm ÷ 30.48 Yards = cm ÷ 91.44
Result: 5 ft 6.9 in
170 cm ÷ 2.54 = 66.93 inches = 5 feet 6.9 inches. Also equals 1.7 meters or 1,700 mm.
The centimeter is the default measurement unit for countless everyday tasks: clothing sizes (European system), body measurements (waist, chest, height), screen dimensions, furniture catalogs (IKEA lists in cm), and school supplies. Its human-friendly scale — one centimeter is roughly the width of a pencil — makes it intuitive for objects between 1 cm and a few meters.
The centimeter was defined in 1795 as 1/100 of the meter, which itself was defined as 1/10,000,000 of the distance from the equator to the North Pole. The inch (2.54 cm) was standardized internationally in 1959 to be exactly 25.4 mm. Before that, British and American inches differed slightly.
The most common cm conversion is human height. A quick reference: 150 cm ≈ 4′ 11″, 160 cm ≈ 5′ 3″, 170 cm ≈ 5′ 7″, 175 cm ≈ 5′ 9″, 180 cm ≈ 5′ 11″, 185 cm ≈ 6′ 1″, 190 cm ≈ 6′ 3″. For precise conversion, divide cm by 2.54 to get total inches, then divide by 12 for feet and use the remainder as inches.
Approximately 0.3937 inches. Or equivalently, 1 inch = 2.54 cm exactly.
Divide cm by 30.48 for feet. Take the remainder and multiply by 12 for inches. Example: 175 cm = 5.741 ft = 5 ft 8.9 in.
1 cm = 10 mm. Centimeters are larger. Most rulers show both: the numbered marks are cm, the small ticks between are mm.
180 cm = 5 feet 10.87 inches ≈ 5′ 11″.
Yes. "cm" is the official SI abbreviation for centimeter.
Using a stadiometer, the patient stands barefoot and the measurement is read in centimeters. This is standard in most countries except the US.
