How to convert

1 meter (m) = 1000 millimeter (mm). Meter (m) is a unit of Length used in Metric system. Millimeter (mm) is a unit of Length used in Metric system.

Meter - Unit of Distance / Length

Unit Symbol / Abbreviation: m

Where the unit used in the World:

The meter is used as a unit to measure medium distances or lengths.
It's a standard measure for short distances (up to 1 km long), in real estate and construction, supply materials, vehicle and aircraft dimensions, short geographical distances and directions in most countries excluding the USA where foot and yard are still widely used for this purpose.
The meter is widely used in most countries and is the official unit for medium lengths and distances (for example, road signs in continental Europe show maximum vehicle hight in meters). Primary exceptions are the United States of America, and some countries where feet and yards are used in limited extent: the United Kingdom and Canada, where the yard remains in limited use as a part of imperial system (for example, yards are used on road signs for shorter distances in the United Kingdom and feet are widely used in construction and real estate in Canada).

Definition of the Unit:

The meter (metre in UK spelling) is a unit of length/distance in the metric system (SI Unit system) equivalent to the length of the path travelled by light during a time interval of 1/299,792,458 of a second (in vacuum, defined since 1983).

1 m is equivalent to 3.28084 ft or 0.000621371 miles.

History of the Unit:

As a result of the French Revolution in 1789, the old units of measure that were associated with the monarchy were replaced by the new units. The new unit of length was introduced which became known as the meter. In 1795 the meter was defined as 1/10,000,000 part of the quarter of a meridian, passing through Paris. The meter gained popularity in continental Europe during the nineteenth century, particularly in scientific field, and was officially adopted as an international measurement unit in 1875. In 1960 the meter was defined as 1,650,763.73 wavelengths of light from a specified transition in krypton-86. In 1983 the final definition of meter was accepted as length of the path travelled by light in a vacuum in 1/299,792,458 of a second.

Where it's used:

The meter is commonly used in different trades and industries (for examle in machinery manufacturing), on road signs to indicate vehicle hight limits, the distance to short travel to a given location (for example in automotive GPS navigation voice prompts), on maps to indicate small scale, for vehicle, vessels and aircragt dimensions in industry and trade. It is also the most popular unit for describing the retail estate distances and measurements (room sizes, floor measurements and so on).

Equivalents in other units and scales:

  • 1 m = 1000 millimeters (mm)
  • 1 m = 100 centimeters (cm)
  • 1 m = 10 decimeters (dm)
  • 1 m = 0.001 kilometers (km)
  • 1 m = 3.28084 feet (ft)
  • 1 megameter = 1000000 m
  • 1 gigameter = 1000000000 m
  • Units of length in the metric SI system are based on multiples or fractions of a meter.
  • There are measurements of length/distance in the metric SI system greater than a meter that can be expressed in terms of metres.

1 m is equivalent to 3.28084 ft or 1.09361 yd.

The meter is a unit of length in the metric SI system and is equivalent to the length of the path travelled by light during a time interval of 1/299,792,458 of a second (in vacuum, defined since 1983).

Meters also can be marked as metres (in British English spelling).

Millimeter: A Unit of Length

Definition of the millimeter

A millimeter is a unit of length in the metric system, which is based on the International System of Units (SI). It is defined as one thousandth of a meter, which is the SI base unit of length. One millimeter can be written as 1 mm or 0.001 m.

How to convert millimeter to other units of length

To convert millimeter to other units of length, we need to use conversion factors that relate the millimeter to the desired unit. For example, to convert millimeter to centimeter, we need to know that 1 cm = 10 mm, so we can divide the number of millimeters by 10 to get the number of centimeters. Similarly, to convert millimeter to inch, we need to know that 1 in = 25.4 mm, so we can divide the number of millimeters by 25.4 to get the number of inches.

Here are some common conversion factors for millimeter and other units of length in the US standard system and the SI system:

  • 1 mm = 0.1 cm
  • 1 mm = 0.03937 in
  • 1 mm = 0.001 m
  • 1 mm = 0.000001 km
  • 1 mm = 0.00000062137 mi
  • 1 mm = 0.00000053996 nmi

Where millimeter is used

The millimeter is a widely used unit of length in many fields and applications around the world. Some examples are:

  • In engineering and manufacturing, the millimeter is often used to measure small dimensions and tolerances of parts and products.
  • In medicine and biology, the millimeter is often used to measure the size and growth of cells, tissues, organs, and microorganisms.
  • In astronomy and physics, the millimeter is often used to measure the wavelength and frequency of electromagnetic radiation, such as radio waves and microwaves.
  • In geography and cartography, the millimeter is often used to measure the scale and distance on maps and globes.
  • In art and design, the millimeter is often used to measure the thickness and width of lines, shapes, and fonts.

History of millimeter

The millimeter has a long and varied history in different countries and cultures. Some historical facts are:

  • The first recorded use of the millimeter as a unit of length was in France in the late 18th century, during the French Revolution. The French Academy of Sciences adopted the metric system as a standard for measurement and defined the meter as one ten-millionth of the distance from the equator to the pole.
  • The millimeter was officially recognized as a part of the SI system in 1960, when the General Conference on Weights and Measures (CGPM) adopted a new definition of the meter based on the wavelength of light emitted by a krypton-86 atom.
  • The millimeter is still widely used today in many countries that have adopted the metric system, such as most of Europe, Asia, Africa, and Latin America. However, some countries still use other units of length alongside or instead of the millimeter, such as the United States, Canada, and the United Kingdom.

Example conversions of millimeter to other units

Here are some examples of how to convert millimeter to other units of length using the conversion factors given above:

  • To convert 5 mm to cm, we divide by 10: 5 mm / 10 = 0.5 cm
  • To convert 12 mm to in, we divide by 25.4: 12 mm / 25.4 = 0.47244 in
  • To convert 100 mm to m, we divide by 1000: 100 mm / 1000 = 0.1 m
  • To convert 250 mm to km, we divide by 1000000: 250 mm / 1000000 = 0.00025 km
  • To convert 500 mm to mi, we divide by 1609344: 500 mm / 1609344 = 0.00031069 mi
  • To convert 1000 mm to nmi, we divide by 1852000: 1000 mm / 1852000 = 0.00053996 nmi
Millimeters also can be marked as millimetres.
