What is one standard atmosphere of pressure in kilopascals?
101.325 kilopascals
Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 103 dynes per square centimetre, 1,013.25 millibars, one standard atmosphere, or 101.325 kilopascals.
What is standard atmospheric pressure in Pascals?
101325 Pa.
Standard atmospheric pressure is usually taken to be 0.760mHg at 0°C. This is a pressure of 101325 Pa.
Is pressure in Pascals or kilopascals?
Pressure Units and Conversion The pascal (Pa) is the standard unit of pressure. A pascal is a very small amount of pressure, so the more useful unit for everyday gas pressures is the kilopascal (kPa). A kilopascal is equal to 1000 pascals. Another commonly used unit of pressure is the atmosphere (atm).
Why is pressure measured in Pascals?
It was named in honour of the French mathematician-physicist Blaise Pascal (1623–62). A pascal is a pressure of one newton per square metre, or, in SI base units, one kilogram per metre per second squared.
How do you calculate pressure in Pascals?
Section Summary
- Pressure is the force per unit perpendicular area over which the force is applied. In equation form, pressure is defined as. P=FA P = F A .
- The SI unit of pressure is pascal and 1 Pa=1 N/m2 1 Pa = 1 N/m 2 .
What is the standard unit of pressure?
Pascal

How do you calculate atmospheric pressure in Pascals?
Solution:
- pressure in Pa = (pressure in atm) x (1.01325 x 105 Pa/1 atm)
- pressure in Pa = (99.136 x 1.01325 x 105) Pa.
- pressure in Pa = 1.0045 x 107 Pa.
How is a kilopascal related to a standard atmosphere?
A kilopascal (kPa) is a decimal multiple of the pascal, which is the SI-derived unit of pressure, stress, Young’s modulus, and ultimate tensile strength. The pascal is a measure of force per unit area, defined as one newton per square meter. A standard atmosphere (atm) is an obsolete non-SI international unit of pressure defined as 101.325 kPa.
How many kilopascals are in a KPA ATM?
Conversion Table atmospheres (atm) kilopascals (kPa) 1 atm 101.325 kPa 2 atm 202.65 kPa 3 atm 303.975 kPa 4 atm 405.3 kPa
What’s the difference between a Pascal and a kilopascal?
Kilopascal : The kilopascal (symbol:kPa) is a non-SI unit for pressure, and is a x1000 multiple of the Pascal unit. 1 kPa equals 1000 Pa. It is not one of the most used pressure units, which is mostly used for describing sub-atmospheric air pressures and low differential air pressures found in building ventilation systems.
Which is the standard unit of atmospheric pressure?
A standard atmosphere (atm) is an obsolete non-SI international unit of pressure defined as 101.325 kPa. For practical purposes, it has been replaced by the bar, which is 100 kPa.
