Re-calculate the original pressure value in Pascal (PA) if it is given in megapascal (MPa). As you know, in one MPa 1 000 000 Pascals. For example, you will need to convert in Pascal 3 MPa, it will be: 3 MPa * 1 000 000 = 3 000 000 PA.

Translate the Pascal in pounds of force, knowing the characteristics of the unit pressure in relation to the unit of force (Newton). One Pascal equals one Newton per square meter. The derived unit of force in Newtons is equal to 1 kg / (m/S2), where m/S2 is the acceleration of free fall. For calculations used the value, which is equal to 9.81 m/S2. Calculate the number of kilograms force of one Newton acting on one square meter with acceleration equal to 9.81 m/S2 : - 1 / 9,81 = is 0.102 kilograms of force per square meter, which corresponds to a pressure of one Pascal.

Multiply the resulting number by the number of Pascals you want to transfer in pounds: 0,102 * 3 000 000 (PA) = get 306 000 (kg/m2). Thus, the pressure value of 3 MPa corresponds to 306 000 pounds of force per square meter. So, to quickly convert Pascals to kilograms, multiply the pressure in Pascals on the coefficient is 0.102. If you need to translate Pascal to kilograms force per square centimeter, the pressure is in Pascals, you need to multiply by a factor 0,0000102. In this example, the pressure of 3 MPa corresponds to 30.6 kilograms force per square centimeter (3 000 000 PA * 0,0000102 = 30,6 kg/cm2).

Note

The magnitude of the gravitational acceleration used to calculate the conversion factor for Pascals to kilograms of force in accordance with Newton's second law (acceleration equals the force of gravity acting on an object of unit mass). The value of the gravitational acceleration in the technical calculations used equal to 9.81 m/S2.

# Advice 2 : How to convert from megapascals to Pascals

Pascal – standard system the unit of pressure. However, in practice, often use other non – si, multiples and sub-multiples of units. This – millimeters of mercury and meters of water column, and atmosphere, bar and kilopascal, megapascal, and millipascal micropascal. To convert these units from one system to another there are special formulas.

You will need

- calculator;
- computer;
- - the Internet.

To convert pressure from

**megapascals**to**Pascals**, multiply the number of Pascals in a million. Ie, use the following formula:CP = ILC * 1000000,where:the ILC – the pressure specified in megapascal (MPa), automatic transmission, pressure in Pascals (PA).2

If no calculator, then transfer

**megapascals**to**Pascals**use pen and paper. To do this, write the number of**megapascals**, and then move the decimal point six digits to the right. Example:1,23456789 -> 1234567,893

If the number of

**megapascals**whole (which in practice happens very rarely), then assign this number to the right six zeroes:12 -> 120000004

If the right of the decimal point is less than six digits, you must add the missing information (up to six) marks the insignificant zeros:123,456 -> 123,456000 -> 123456000, -> 123456000

5

If, after the transfer of the decimal point in the left part of the number formed of "excess" zeros, just drop them:0,000123456 -> 0000123,456 -> 123,456

If there is no calculator, no paper, try to do all of the above calculations are "in the mind". However, it is necessary to be very careful, since the error only on one position means the distortion of the result in ten times!

If you have access to the Internet, to transfer

**megapascals**to**Pascals**or other units of measurement, use the corresponding online service. To do this, type in any search engine query of the type: "translate mega**of Pascal**" or "Pascal pressure." Then use the on site instructions. For example, open a page http://www.convertworld.com/ru/davlenie/Паскаль.html. On it you will see a row consisting of three Windows. The first of them will need to enter the number of**megapascals**, and the second select unit of measurement (megapascal), and the third to specify the precision (number of digits after the decimal point) of the result. All versions of convert (without confirmation) immediately appear at the bottom of the web page.
