How long is a metre squared

Square metres, sq m and sometimes sq mtrs are all used to denote the same thing, a unit of area. The International System was set up so that we all use the same units, names, symbols etc. For area that means square metres. This not straightforward. As well as wanting students and teachers to learn and follow the established international convention in this case, I find that students tend to understand the subjects of area and volume better when they do.

In what ways do you think it is wrong. What is your background that tells me that I am wrong. I am happy to discuss this. Edward Murphy is quite correct.

You are wrong. They are completely different. My background? Electrical engineer, engineering lecturer and author, masters degree. I beg to differ. This is not wrong and it is not scientific to show the difference as Ken has shown, although perfectly OK in ordinary everyday life terms. BIPM have a website and the info is on there. Nobody remotely serious in science would contradict the BIPM on this subject.

No problem. Having experienced the disbelief myself — even in schools where other teachers joined in with the disbelief — I had to help. Further to my comment, how would you express the unit for acceleration? This has to do with the fact that geometric units areas and volumes have the adjective before, while non-geometric units have the past participle after the underlying unit. Not in actual area, but in shape.

Completely different though when it is 2 square metres against 2 metres square d. One remains 2 square metres, the other is 4 square metres. If things have changed in the ensuing almost 48 years, I have no idea. And before I forget, to forego any further confusion as to what is what, 1 square metre should be written down as 1sqm, 1 metre square d should be written 1msq.

Preferable it should be written out fully, but what would I know, leaving school at age 15? Not quite true. The SI derived unit for area is the square metre at least in English, it may be translated in other languages , and m with a superscript 2 is the symbol for that unit, and such symbols are used internationally, regardless of local language. The SI unit of area, Standard Internationale is the square metre m2, where the 2 is a subscript. Unfortunately in the UK the priority seems to be maintaining a ratio of students to teachers, with inevitable consequences in quality control.

Well if that is your experience then it is quite sad. My niece has just started teaching in England and she had excellent grades in Maths and further maths A level and did an economics degree. Hmm, SO confusing!! Or BOTH. Am I as confused as I feel or have I just made sense? Thanks for your contribution to the debate Brendon, and I am certainly more confused by the middle bit of your post!

Area can be any shape. There are indeed 10 cm2 in 1 m2. Now as a cartoonist, your task is to explain that to the world! This is by far the most popular post of my complete site, so see what you can come up with and hopefully you can get some commissions, should you require them. Keep safe! However, the issue here actually only applies to geometric non-linear units i. Convert from centimetres to metres. Multiply the length and width together. Once both measurements are converted into metres, multiply them together to get the measurement of the area in square metres.

Use a calculator if necessary. For example: 2. Round to a more convenient measurement. If you get a long decimal as an answer, for instance, 2. In most cases, you can round to the nearest centimetre 0. Whenever you multiply two numbers with the same units for instance, metres , the answer is always in the form of that unit squared m2, or square metres.

See above for instructions on how to find the area of a right triangle; measure each of the two sub-triangles separately, and add them together.

Calculate the area of a circle. If you're not sure where the center is, have a friend hold a tape measure and walk around the edge of the circle. Hold the other end of the tape measure and adjust your position until the measurement stays the same while your friend walks around the entire edge.

More complicated curved boundaries require more advanced math to calculate. If you are measuring a room for practical purposes, it might be easier to estimate the area by pretending the curved surfaces are a series of straight lines.
