How to convert square millimeter

In 1960 adopted the international system of units SI (System International). For the needs of science and technology this system was introduced 7 base units: meter, kilogram, second, ampere, mole, Kelvin and Candela, as well as their derivatives. The same for the whole world units greatly facilitate the understanding of scientists of all countries. Difficulties arise only when the values more or less than is commonly SI. And this happens often. For example, the area of the countries measured in square kilometers, and the cross-sectional area of the electric cable in square millimeters.

Instruction

For translation in square millimeters square meters look closely at the word "millimeter" more closely. It consists of two parts. The root "meter" is a unit of length in SI. The prefix "Milli -" means a thousandth of something, and is the literal entry of a decimal multiplier: 0.001 or 10^-3. Conditionally write it like this: 1mm=10^-3M. thus, any length, expressed in millimeters, can be represented as follows: Hm = X•10^-3 M. for Example: 27mm=27•10^-3M.

Square millimeter is a millimeter, multiplied by the millimeter, or 10^-3M squared: mm^2= (10^-3) ^2 m^2=10^(-3•2) m^2=10^-6m^2. Ie, instead of the first letter "m" (miles), write "10^-6".For example: 51mm^2= 51• (10^-3) ^2 m^2=51•10^-6 m^2.

The same method give not only SI millimeters squared, but in Cuba and in any other degree. Example: 394мм^3=394•(10^-3)^3 m^3=394•10^-9 m^3, 68mm^-6=68•(10^-3M)^-6 m^-6=68•10^18 m^-6.

In this way translate into various degrees and other fraction and multiples of a meter.For example: 79cm^3=79•(10^-2m)^3 m^3=79•10^-6 m^3, 422 km^2=422•(10^3M)^2 m^2=422•10^6 m^2.

Note

In forest and agriculture area is measured in hectares (ha). Remember that 1 hectare=1•10^4 m^2

Useful advice

For translation, the SI note the multipliers and prefixes that are most often used:
10^9 – Giga,
10^6 – mega-,
10^3 – kilo,
10^-1 – deci-,
10^-2 – centi-,
10^-3 – Milli-,
10^-6 – micro.

Is the advice useful?
