Convert centimeters (cm) to square centimeters (cm2)

About cm to sq cm calculator and how to convert:

 

Converting from square meters to square centimeters is straightforward. A square meter is equivalent to 10,000 square centimeters. To convert, simply multiply the area in square meters by 10,000. And to revert back, divide by 10,000. It's that simple.

 

Box length – 342 cm, Box Width – 215 cm;

Area, which is filled by the box = 342cm x 215cm = 73, 530cm2;

 

Now, let's round to a two-digit number after the decimal point—73 000 cm2. Often, the result is not presented as an integer—it reflects both centimeters, and millimeters or meters. Therefore, you need to convert centimeters to meters or to millimeters. Then, it will be easier to multiply the numbers. 

 

Another example is that we have a box with equal sides of 40 centimeters. One centimeter is equal to 0.01 meter. The conversion is done using a simple technique – moving the decimal point of "0.01" back two digits (to the left). May this square centimeters example will help you understand more what is it about.

 

40 cm = 0.4 m. The area in sqcm = 0.4m *0.4m = 0.16sqm = 0.16 / (0.01 *0.01)  = 1600 sqcm. So it is easy to convert sqcm to cm, and cm to sqcm. Formulas are easy.

 

Of course, it will be convenient to count - if you take a 100-centimeter tape or a tape measure — you will need to convert the resulting numerical values ​​​​into centimeters. Precisely length and width measurements are carried out from one point (angle) to another, opposite point (angle). If the resulting number is not an integer, then not only is the le amount of tapes counted, but they also  fraction parts of the tape.

 

Example: We have three tapes and a half for an equal-sized tile. The needed area for the tile is equal to (35 * 100 cm) * (35 * 100 cm) = 1225 cm2. When the numbers are less than one centimeter, rounding is done to the nearest square centimeter.  Lets round to 1200cm2. Let's take again the value of 1225 cm2. But when installing a frame, absolute accuracy is essential. Therefore, everything is verified. This is especially true for cabinets built into wall niches. So if you need, do not round.

Now about triangle. You can find the area of ​​​​a triangle with a right angle in a simple way:

• measure the sides that form an angle of 90°;
• multiply the numbers;
• divide by 2 and get the square meters of the triangle.

 

Other triangles can be calculated by visually drawing a line from any vertex that forms a right angle on any side. 

 

You can find the area of ​​a circle using the formula π x R2, where π is a constant (3.1415926535), and R2 is the digital value of the radius to the second power.
