What Is millimeter (mm)

The millimeter is one of the units of length in the International System of Units (SI); one millimeter equals one thousandth of a meter, and there are one thousand millimeters in a meter. There are ten millimeters in a centimeter.

When do you need to use millimeters as a unit of measurement?

The application of millimeters is mainly used when the measurement of centimeters cannot be expressed or when more precise results are desired, and the value of millimeters may be retained to three decimals when it is necessary to measure and express it with greater precision. For example:

The diameter of the head of a large-head pin is about 2.1 millimeters.

Small-port ammunition for the Uzi assault rifle is 9 mm in diameter.

The thickness of a CD disk is about 1.3 millimeters.

A barber can do precise cuts of hair about 3 mm long (6 mm, or 9 mm, etc., depending on the type of barber)

Weather stations also use millimeters as the unit for measuring rainfall over a 24-hour period; when under 10 millimeters it is called light rain, when 10.0-24.9 millimeters it is considered moderate rain, when 25.0-49.9 millimeters it is considered heavy rain, torrential rains are generally 50.0-99.9 millimeters, and heavy rainfall is 100.0-250.0 millimeters, and rainfall in excess of 250.0 millimeters is referred to as extraordinarily heavy rainfall.

Relationship between millimeters and centimeters, decimeters and meters

1 millimeter (mm) = 0.001 meter (m)

1 millimeter (mm) = 0.01 decimeter (dm)

1 millimeter (mm) = 0.1 centimeter (cm)

1000 millimeter (mm) = 1 meter (m)

100 millimeters (mm) = 1 decimeter (dm)

10 millimeters (mm) = 1 centimeter (cm)

What is Inch?

The word “inch” comes from the Old English “ynce”, which is also the Latin “uncia” (meaning “one twelfth”). The word “inch” comes from the Old English “ynce” and the Latin “uncia” (meaning “one-twelfth”), which in Dutch originally meant thumb, and at that time meant that one inch was the length of one thumb. Of course, the length of a human thumb varies. It belongs to the British system of length measurement, is only in the United States and other very few countries are still used, it is defined as 1/36 yards, or 1/12 feet, in the 14th century, King Edward II promulgated the “standard legal inches”. The regulation is: from the middle of the barley spike to select the three largest grains of wheat head to head in a row length is 1 inch. Before the definition of inches is more confusing, different countries have different standards are quite different, until the last century after the adoption of the international code in the 1950s and 1960s, inches to metric units based on the precise definition of 25.4 millimeters, that is, 2.54 centimeters.

In daily life, the size of the display of our electronic products is usually measured by the length of the diagonal line, in “inches” as a unit. Calculate the number of inches of the screen of electronic products is: measure out the screen diagonal how many centimeters, and then the number of diagonal centimeters divided by 2.54, you can know how many inches of the screen.

Common conversions between inches and metric units of length:

1 inch = 2.54 centimeters;

1 inch = 25.4 millimeters;

1 inch = 0.254 decimeters;

1 inch = 0.0254 meters;

1 meter = 39.37 inches;

1 decimeter = 3.937 inches;

1 centimeter = 0.3937 inches;

1 millimeter = 0.03937 inches.
