Como esta calculadora funciona?
Divide centimeters by the target unit's factor to convert: cm ÷ 2.54 = inches, cm ÷ 30.48 = feet, cm ÷ 100 = meters, cm × 10 = millimeters. All factors are exact international definitions. Enter the length and pick a unit to see all key conversions at once.

How this is calculated
Every length unit has a fixed conversion factor relative to the centimeter, established by international agreement. One inch is defined as exactly 2.54 cm, one foot as exactly 30.48 cm, one yard as exactly 91.44 cm, and one international mile as exactly 160,934.4 cm. These are exact definitions — not approximations — so conversions are precise and reversible without rounding drift.
To convert from centimeters to any target unit, divide the centimeter value by the target unit's factor. For millimeters, multiply by 10 (since 1 cm = 10 mm). For meters, divide by 100. The reference table below always shows the four most common targets — mm, in, ft, m — so you can compare the same length across unit systems at a glance.
The number line shows the input length on a millimeter scale, giving an intuitive sense of magnitude. Very large inputs (hundreds of meters) will compress the scale; the underlying math stays exact regardless of display rounding.
Perguntas frequentes
1 centimeter equals exactly 1 ÷ 2.54 ≈ 0.3937 inches. So 10 cm ≈ 3.937 in, 30 cm ≈ 11.81 in, and 100 cm = 1 m ≈ 39.37 in.
First divide cm by 2.54 to get total inches. Then take the integer part ÷ 12 as feet and the remainder as leftover inches. For example, 180 cm ÷ 2.54 ≈ 70.87 in = 5 ft 10.87 in.
There are exactly 100 centimeters in 1 meter — the prefix "centi" means 1/100. To convert cm to meters, divide by 100; to go from meters to cm, multiply by 100.
