A square millimeter (mm2), sometimes written as sq mm, is a unit of area in the metric system.
It represents a tiny area equal to one-millionth of a square meter (10-6 m2).
A square millimeter is a minuscule unit of area, representing a square with sides that are each one millimeter long.
To put its size into perspective, the head of a common pin is approximately one to two square millimeters. A single grain of fine sand can also cover an area of about one mm2.
This small scale makes it the ideal unit for measuring minute surfaces with high precision.
The square millimeter is a crucial unit in many technical and scientific fields. Its precision is essential for:
As part of the International System of Units (SI), the square millimeter relates directly to other standard units of area, making conversions straightforward.
The most common conversions are:
This simple, base-10 relationship is a key advantage of the metric system, particularly in scientific and international contexts.
