Pressures less than 0 kPa are called negative pressures. They indicate a pressure lower than atmospheric pressure.
These data are very variable around the world.- IUPAC recommendations:a) 0 oC and 100 kPa orb) 25 oC and 100 kPa- NIST recommendation:20 0 oC and 101,325 kPa- methane gas measurements: 15 oCand other values also exist.
STP Standard Temperature and Pressure 0 degrees C and 101.3 kPa pressure
At 0 m (sea level), where New Orleans lies, barometric pressure is around 101.33 kPa. The city of Chihuahua in northern Mexico has an altitude of 1433 meters (4698 feet) above sea level. At such altitude, pressure is around 86 kPa.
At standard pressure (100 kPa), dry air at 0 °C has a density of 1.2754 kg/m3 or 1.2754 g/L. Changing the composition, pressure, temperature or humidity changes the density.
To convert 255 mL of CO2 from 30°C and 85.0 kPa to STP (0°C and 101.3 kPa), you can use the combined gas law. First, convert the temperature to Kelvin (303 K) and pressure to atm (0.85 atm), then use the formula: (P1V1/T1) = (P2V2/T2) to find the volume at STP. This calculation will show that at STP, the volume of 255 mL of CO2 would be approximately 241 mL.

0.6 kPa
To convert inches of water to kilopascals (kPa), multiply the value by 0.2488. Therefore, to convert 0 to 7 inches of water air flow to kPa, multiply each value by 0.2488 to get the equivalent air flow in kPa.
After IUPAC rules the temperature is 0 0C and the pressure 101,325 kPa.

The vapor pressure of octane at 0°C is approximately 3.8 kilopascals.
Front Air Pressure 11-17psi (80-120 kPa, 0.8-1.2 kg/cm) Rear Air Pressure 0-70psi (0-500 kPa, 0-5.0 kg/cm) per the 1982 Honda GL500 owners manual.
An angle less then 90° is called an acute angle.
