One unit of MPa corresponds to one million Pascale. This indicator is used for measurement of physical pressure or mechanical tension in IS (international system) - the International System of Units which is modern option of the metric system and is most widely used around the world. The MPa can be transferred in various units, including in kilograms.
Instruction
1. For designation MPa figure 10 in the sixth degree is also often used. The pascal is equal to pressure, which is created by force in one newton to a surface of 1 square meter, evenly distributed on normal to it. The unit of measure of pressure was called in honor of the French mathematician and the physicist Blaise Pascal. Formally pressure unit (1 Pa = 1H/m²) coincides with energy density unit (J/m³), that is with amount of energy per unit of volume (or per unit mass). However they describe different physical properties and therefore, in terms of science, are nonequivalent. In this regard it is incorrect to write down pressure as J/m³, and Pascal to use unit for measurement of density of energy.
2. So, Pascal is pressure is one Newton on square meter of the area. Newton – force unit of measure, is defined how force which changes to 1 meter per second the speed of a body weighing 1 kilogram per the unit of time equal to one second. The formula looks as follows – 1H = 1kg*m/with². This situation follows from the second law of Isaac Newton, the famous English physicist, the astronomer and the mathematician.
3. In practice it is the best of all to transfer Pascals to Newtons by means of a weight formula – P = to mg. Here m is a weight, and g is an acceleration of gravity which equals 9.8m/with². It is powerful in physics call force operating on a support which interferes with falling. It is measured in the size showing pressure of one Newton upon 1 m² - 1 Pa = 1H/1m². Thus, having substituted the first expression in the second, you receive the size of Pa approximately equal 100 gr. Further increase both parts of expression by one million for construction of Pa in MPa. As a result it will turn out that one million Pascals (1 MPa) are hundred thousand kilograms or 100 tons, i.e. to such force there is pressure in 1 MPa upon 1 m² of a surface.
