What is Kilopascal?

The kilopascal equals 1,000 pascals and is commonly used for tire pressure specifications. A typical passenger car tire is inflated to about 220 to 250 kPa. Some blood pressure monitors also display readings in kilopascals. In industry, gas pipeline pressures and hydraulic system pressures may be expressed in kPa. Standard atmospheric pressure is approximately 101.325 kPa.

What is Atmosphere?

The standard atmosphere is a unit of pressure defined as exactly 101,325 pascals. It approximates the average atmospheric pressure at sea level on Earth. In diving, pressure increases by roughly 1 atm for every 10 meters of water depth, so at 30 meters the total pressure is about 4 atm. In chemistry, standard conditions for gases are defined at 0 degrees Celsius and 1 atm, making it a fundamental reference in thermodynamics and gas law calculations.
