To put pressure set in Pascal, in kilopascals, multiply the number by 0,001 Pa (or divide by 1000).In a formula, this rule can be written as follows:
PAC = R * 0,001
or
PAC = R / 1000,
where:
PAC - the number of kilopascals,
K - the number of Pascal.
PAC = R * 0,001
or
PAC = R / 1000,
where:
PAC - the number of kilopascals,
K - the number of Pascal.

Example: normal atmospheric pressure is considered to be equal to 760 mm Hg.st., 101325, or Pascal.
Question: How kilopascals equals normal atmospheric pressure?
solution: divide the number per thousand Pascals: 101325/1000 = 101,325 (kPa).
Answer: normal atmospheric pressure equal
s 101 kPa.
Question: How kilopascals equals normal atmospheric pressure?
solution: divide the number per thousand Pascals: 101325/1000 = 101,325 (kPa).
Answer: normal atmospheric pressure equal
3
to divide the number per thousand Pascals, simply move the decimal point three digits to the left (as in the example above):
101325 - & gt;101,325.
101325 - & gt;101,325.

If the pressure is less than 100 Pa, then put it to kilopascals ascribe to the number of missing zeros to the left.
Example: How much will the pressure in kilopascals one pascal?
Resolution: 1 Pa = Pa 0001 = 0,001 kPa.
Answer: 0,001 kPa.
Example: How much will the pressure in kilopascals one pascal?
Resolution: 1 Pa = Pa 0001 = 0,001 kPa.
Answer: 0,001 kPa.

When solving physics problems, note that pressure may be set in other units of pressure.Very often in the measurement of pressure occurs, such as the unit of N / m (Newton per square meter).In fact, this unit is equivalent to Pascal, as is its definition.

Officially, unit Pascal (N / m) is equivalent to the units of energy density (J / m).From the physical point of view, these units describe different physical properties.Therefore, do not write the pressure as the J / m³.

If the problem appears in a variety of other physical quantities, the transfer of Pascal kilopascals made at the end of the solution.The fact that Pascals - a system unit and, if the other parameters are included in SI units, and the response is received in pascals (unless defined pressure).
