Conversion Formula
1 millimeter (mm) = 0.001 meters (m)
To convert millimeters to meters:
meters = millimeters × 0.001
Example: 2500 mm × 0.001 = 2.5 m

Definition and Background
What is a Millimeter?
A millimeter (mm) is a metric unit of length equal to 0.001 meters. The name comes from:
- Latin “mille”: meaning thousand
- Greek “metron”: meaning measure
What is a Meter?
The meter (m) is the base unit of length in the International System of Units (SI). It was originally defined in 1793 as:
- 1/10,000,000 of the distance from the equator to the North Pole
- Now defined by the speed of light (1/299,792,458 of a second)

Frequently Asked Questions
Why would I use millimeters instead of meters?
Millimeters provide a precise unit for measuring small distances or objects, ideal for applications requiring high accuracy, such as engineering and design.
How precise is millimeter measurement?
Millimeters are highly precise (1 mm = 0.001 m), making them suitable for detailed measurements where accuracy is critical.
What’s the history of the millimeter?
Introduced during the French Revolution as part of the metric system, from the Latin “mille” (thousand) and Greek “metron” (measure).
Are millimeters used worldwide?
Millimeters are widely used globally in countries that adopted the metric system, especially in technical fields, though less common in everyday use in the US.
