Millimeters and centimeters are both units used to measure length. Keep reading to learn more about each unit of measure.
The millimeter, or millimetre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "milli" is the prefix for 10-3. Millimeters can be abbreviated as mm; for example, 1 millimeter can be written as 1 mm.
The centimeter, or centimetre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "centi" is the prefix for 10-2. Centimeters can be abbreviated as cm; for example, 1 centimeter can be written as 1 cm.
Metric rulers typically have 30 cm, which are represented by 30 large tick marks. To get a rough idea of the actual length of a centimeter, a standard pencil is just about 1 cm thick.
We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or combination with both values, so make sure you get the correct type for your needs.
