1 M to MM – 1 Meters to Millimeters

In this post, we will demonstrate how to convert 1 meters to millimeters (1 m to mm) and will provide you multiple ways to accomplish this. One is using our online m to mm converter, which works for any given number of meters. Another is using a 1 m to mm conversion chart for the exact value of 1 meters. A third is manually calculating this using conversion factors. All three methods will give the same answer: 1 meters = 1000 millimeters.


1 m to mm Converter

Enter the number of meters (ex. 1) that you want to convert to millimeters in the box below. This converter is not limited to only converting what 1 meters is in millimeters, but it works for any number of meters that is input.

The distance will automatically be converted to millimeters without you needing to click anything else. To clear the values, you may click the ‘reset’ button. Note that this converter only works for changing meters to millimeters, and not the other way around.

Note: The converter automatically convert meters to millimeters. You just have to enter a value in the field. The converter cannot swap units.


1 m to mm – Unit definition


Definition of Meter

A meter (abbreviated as m) is a unit of distance that serves as the basic unit of length in the metric system and the International System of Units (SI). The SI defines a meter as the distance light travels in 1/299,792,458 seconds while it is in a vacuum.

The meter has had several historical definitions, including a fraction of the distance from the equator to the North Pole, the length of a prototype bar, and a multiple of the wavelength of the emission line of krypton-86. This is also spelled as metre in British English and the original French spelling.


Definition of Millimeter

A millimeter (abbreviated as mm) is a unit of distance. Following the use of prefixes in the metric system, the prefix milli- indicates a fraction of 1/1000 of the original base unit, so a millimeter is defined as 1/1000 of a meter. This is often used in measurement of small objects that are no larger than a person’s hand, and the millimeter is often used in engineering practice to measure dimensions of small mechanical and electrical parts that are used as components in larger assemblies and machines. This unit of measure is frequently used in the same countries that use the meter, such as the US and the UK.


1 m to mm – Conversion Chart

In case you do not have the time to use the converter and input the number yourself, you can use a 1 meters to millimeters conversion chart to see the final result immediately. This result has been calculated ahead using the converter, so the result will be the same.

Unit Conversion Meters (m) Millimeters (mm)
1 m to mm 1 m = 1000 mm


1 meters (m) to millimeters (mm)

In the previous sections, we have presented two options for converting 1 meters to millimeters. The first option was to use our online converter. However, there may be times when one does not have access to the internet, or specifically to this webpage.

The second option was to use a 1 m to mm conversion chart, which saves any effort because it already has the final value. But like any conversion chart, its use is limited to that single value, and furthermore, one may not always carry conversion charts around with them. Therefore, it is beneficial to know how to do this conversion manually, using a hand calculator.

The succeeding sections describe the manual procedure to convert meters to millimeters. Like the converter, this is a general procedure and can be used to convert any number of meters to millimeters. For this case, where we wish to convert 1 meters to millimeters, we will use this manual procedure and show that the result is the same as those obtained using the online converter and the conversion chart.

This process can then be extended for any other length in meters, to convert the given distance to millimeters. We will use the definitions given earlier to carry out this conversion.

Most common m to mm (Meters to Millimeters) conversions:


Convert 1 m to mm

In the above section containing the definitions, a millimeter has been declared equivalent to 1/1000 meters. This means that there is a constant proportion between the two, so just as 1 millimeter is equivalent to 1/1000 meters, multiplying both values by the same number will still give a true statement. For example, if we were to multiply both numbers by 2, then:

1 millimeter multiplied by 2 would become 2 millimeters, and

1/1000 meters multiplied by 2 would become 2/1000 meters

The new numbers are still equivalent, that is, 2 millimeters is equivalent to 2/1000 meters.

Another way to look at this conversion factor is that if 1 millimeter is equivalent to 1/1000 meter, we can multiply both numbers by 1000:

1 millimeter multiplied by 1000 would become 1000 millimeters, and

1/1000 meters multiplied by 1000 would become 1 meter

Therefore, 1000 millimeters is equivalent to 1 meter.

Based on this statement, since we want to convert 1 meters to millimeters, we can multiply both these values by 1 to get our desired result.

This means that 1 meters (m) is equivalent to 1000 millimeters (mm).


1 m is equal to how many mm?

The above calculations show that when we convert 1 meters to millimeters, we get the result of 1000 millimeters or 1000 mm. This final answer is obtainable by all three methods we have presented. From our first method, entering in 1 meters in the 1 m to mm online converter will give this answer of 1000 millimeters (mm). Our second method, the 1 m to mm conversion table, shows the same result of 1000 millimeters (mm).

Our third method is much more detailed as it shows the step-by-step manual calculation of how to convert 1 meters to millimeters. It begins by using the definition of the meter in terms of millimeters, and using the conversion factor 1,000 mm to 1 m, creates a new proportion using the given of 1 meters. This method also arrives at the same answer of 1000 millimeters (mm).

All three methods used agree on the same answer, and so it is up to the reader’s discretion which of the three methods is preferable. The online 1 m to mm converter is simple to use, provided one has access to this webpage.

A conversion chart can be printed out and carried around for convenience, but only specific values can be recorded on it (it would be difficult to record every possible value, especially those involving decimals, on it). Finally, the manual calculation method may be difficult to understand at first, but once it has been learned, anybody can use it anytime, to convert any number of meters into millimeters.
