There are different measurement systems and among them a relationship that allows us to convert units within the same system or between two different ones. For example, when we work within the Decimal Metric System, we can convert meters to centimeters, which implies multiplying by 100 the amount we want to convert, or if we want to convert meters to millimeters, we will always multiply by a thousand. These numbers to multiply by are called conversion factors. If we wanted to convert centimeters into meters we would multiply by 0.01. We see that within the metric system the conversion factors are always multiples or submultiples of 10.
The Anglo-Saxon system uses another type of units of length, these are measurements that are related to the human body, called anthropometric units, such as the inch (length of the first phalanx of the thumb), the foot, the yard (distance between the tip of the nose and the tip of the middle finger with the arm extended), the breaststroke (distance from tip to tip between the middle fingers with the arms extended), the span (length of the palm of the hand), the elbow (length of the forearm). They are called anthropometric units.

Instructions to convert centimeters to inches
- All these measurements related to the human body give the idea of being variable because it will depend on each body, on each person, but when this unit of measurement was instituted, a certain one was adopted, perhaps from whoever invented it. The inch was applied in the Anglo-Saxon countries for small measurements, for longer distances the foot is used, which logically is the length that that person has or had or the fathom according to the need to measure.
- The Anglo-Saxon inch is equivalent to 25.4 mm or 2.54 cm and is symbolized with in which comes from the English word inch or with the quotation marks:”.
- That is to say that: 1” = 2.54 cm
- 2” = 2.54 x 2 cm = 5.08 cm
- 3” = 2.54 x 3cm = 7.62cm
- 10” = 2.54 x 10cm = 25.4cm
- 100” = 2.54 x 100 cm = 254 cm
- The conversion factor to convert from inches to centimeters is 54. Any measurement you have in inches, when multiplied by 2.54 you will get it in cm
- Let’s see the opposite passage, if you want to convert centimeters into inches you must divide the amount by 2.54 or, what is the same, multiply it by 0.393700787. In other words, (approximate). If you want to work with more precision, you should consider the number with the most decimal places (0.3937).
- For example: 1cm = 0.39”
- 2cm = 0.39 x 2” = 0.78”
- 3cm = 0.39 x 3” = 1.17”
- 10cm = 0.39 x 10cm = 3.9”
- 100cm = 0.39 x 100cm = 39”
- If you have a computer with an Internet connection you can search for any of the unit converters and do it quickly. For example go to:
- If you open this converter you will see that you have a box to enter the amount in cm you want to convert and you will automatically get the result. You can select if you want the measurement in decimals or fractions. For example, in the photo you see the equivalence between 15 cm and 5.9055 inches.
- There you place the measurement in centimeters and then “convert” and you already have the results. You will see that you can also do the opposite way, that is, convert inches to centimeters. For this, mark the point where it says “convert to centimeters”, then place the amount in inches and you will get centimeters.
