There are 39.37007874 inches in a meter.
You can use any of the following methods to carry out meter to inch conversion.
Method 1:
This method uses multiplication to convert meters into inches.
Number of meters × 39.37007874 = Value in inches
For example, let's convert 2 meters to inches:
2 m = 2 × 39.37007874 in
∴ 2 m ≈ 78.7402 in
Method 2:
This method uses division to convert between meters and inches.
Number of meters ÷ 0.0254 = Value in inches
For example, let's convert 3 meters to inches:
3 m = 3 ÷ 0.0254 in
∴ 3 m ≈ 118.11 in

What is the meter?
The meter is the base unit of length in the SI unit system, which is the current standard of the metric system. It is used to measure the lengths of medium to large objects and distances that are not too long. We have been using different scales and tools to measure lengths and distances in meters, but how was it defined and determined how long a meter would be? Let's find out in the next section.
History of the meter
From ancient times, we have been measuring the length of objects. The earliest known measurement methods used the lengths of our body parts, such as the foot, hands, fingers, arms, etc. However, these methods needed more accuracy and precision due to the differences in the size of human body parts from person to person. Thus, the idea of building a universal measurement system arose in France.
To achieve this, a council of scientists and mathematicians established by the French Academy of Sciences proposed a decimal-based measurement system in 1791. As per recommendations, the units of various quantities like length, volume, and mass were defined. The name meter was borrowed from the Greek word metron, meaning "a measure". The meter length was determined as the ten-millionth of the distance of the line between the North Pole and the equator, passing through Paris in France.
To realize this definition, a geodetic survey was conducted between 1792 and 1798 between Dunkirk, France, and Barcelona, Spain. The final measurement was submitted to the academy in 1799, and a platinum bar was embodied based on this measurement to define the length of a meter. This newly defined system of measurements, introduced in France, was called the metric system and was gradually adopted in other parts of the world.
In 1875, the Treaty of the Meter was signed by 17 countries, including the United States. As a result, the International Bureau of Weights and Measures (BIPM) was established.
In 1889, a new meter prototype, a bar made of platinum and iridium with an X-shaped cross-section, was developed for better durability and adopted as the international prototype of the meter. The length of the meter was determined by the distance between two endpoints of this platinum-iridium bar at the standard atmospheric pressure at the melting point of ice.
In 1960, the definition of the meter was again changed. The length of a meter was defined as 1,650,763.73 wavelengths in the vacuum of the radiation corresponding to the transition between certain levels of a krypton 86 atom. This was when the metric system was changed to its current standard, the International System of Units (SI).
Note that every time the meter is redefined, the actual length of the meter remains unchanged. These changes in the meter definition are made to avoid any challenges that may arise in the future in sustaining the original meter length. For example, the platinum bar initially embodied to realize the meter length could have been damaged, lost, or stolen in the future. In that scenario, a solid definition of the meter was required so that anyone could easily create a meter prototype using that definition.
The meter was again redefined in 1983 based on the speed of light to achieve more accuracy. Keeping the same meter prototype as the reference, scientists noted that the light in a vacuum travels the exact distance equal to the length of a meter in 1/299,792,458 seconds, and that was made the standard definition of the meter. This also defined the speed of light in a vacuum as 299,792,458 meters per second. The 1983 definition is the most accurate definition of the meter so far and is still in use.
What is the inch?
The inch is a unit of length in the British Imperial System and the United States Customary Units system. It values 1‾12 of a foot. The SI equivalent value of an inch is 2.54 centimeters or 0.0254 meters. Like centimeters, it is also used to measure the lengths of small objects or small distances, mainly in the United States, Canada, and the United Kingdom.
Where did the modern inch come from?
The unit inch was borrowed from the Roman unit uncia. Uncia is a Latin word meaning one-twelfth. A Roman uncia or Roman inch was equal to 1‾12 of a Roman foot.
Common applications of the inch
Some widely used applications of inches include the electronics and the automotive industry. In the electronics industry, display screens are measured in inches worldwide. In Japan, electronic parts are officially measured in inches. In the automotive industry, the diameter of vehicle wheel rims and the inner diameter of tires in tire codes are commonly measured in inches.
Technical information about the inch
The inch is symbolized as in, but in practice, it is also denoted by double quotes ". Unlike SI units, which are divided into the units of tens, an inch is divided into quarters, eights, and sixteens. That is, dyadic fractions are used to express portions of an inch. For example, four and five-eighths of an inch are written as 4 5‾8" instead of 4.625", and 0.25 inch is written as 1‾4". In engineering applications, inches are typically written in decimal format with three to four decimal places.
How long is an inch?
Compared to centimeters, an inch is 2.54 centimeters long. However, by looking at some day-to-day objects around us, we can get an idea of how long an inch is.
For example,
Standard measurements that use the inch as the unit of length
Several standard measurements use the inch as their unit.

Here are some standard measurements that use fixed-inch values.
How many meters are in an inch?
There are 0.0254 meters in an inch.
How to convert meters to inches?
You can achieve meter to inch conversion by one of the following approaches.
First, you can multiply the number of meters by 39.37007874 to get the value in inches.
Second, you can divide the number of meters by 0.0254 to convert meters to inches.
