VIDEO: Convert qcm to qm

qcm and qm - outdated unit symbols

If you use the abbreviation "qm" or Read "qcm", it is nothing more than an outdated unit for square meters or Square centimeters, i.e. the specification of an area.

• Square meters or Alternatively, square centimeters can also be used as "meters to the square" or Denote "centimeters squared".
• For example, with an area of ​​one square meter or one square centimeter, the side lengths of a square are one meter or one. an inch long.
• Since the introduction of the SI system of units (French for "Système international d’unités"; in German "International System of Units") these symbols are no longer permitted. Instead, the areas for “m x m” are displayed as “m²"And for" cm cm "as" cm²“Shown.
• For the display on the computer there was the problem at the beginning that the superscript 2 was not displayed correctly could, so that the spelling “(c) m ^ 2” or “(c) m2” was used and is still partly used today come.

Quickly and easily convert qcm to sqm

If you have problems imagining a conversion from qcm to sqm, then just start:

• Remember that when calculating the area of ​​a square or rectangle, you have to multiply two adjacent sides.
• For the conversion of the side lengths you simply have in mind that 100 centimeters is exactly 10 decimeters or 1 meter.
• Since you have to multiply the lengths of the sides to calculate the area, you have to do the same for the conversion values. Accordingly, 10,000 square meters (100x100cm) are exactly 100 square meters (10x10dm) or 1 square meters (1x1m). That means, one square meter corresponds to 10,000 square centimeters or In other words, 10,000 square centimeters is exactly one square meter.
• So when converting square meters to square centimeters, you simply have to add four zeros, and when converting square centimeters to square meters, subtract four zeros.

Conversion based on an example

For example, if you have an area of ​​10cm² you need to do the following:

1. Think of multiplying the two sides and converting centimeters to meters (100). This gives you the conversion value of 10,000 (100x100).
2. This means that you simply have to shift the output value four places (= 4 zeros) to the right. This would then be 1 in steps; 0,1; 0.01 and 0.001. Accordingly, 10cm would be the same² exactly 0.001m².
3. Alternatively, you could simply divide the initial value by 10,000, which would also result in a final value of 0.001m² come.
