Standard sea-level conditions
Standard sea-level conditions (SSL), also known as sea-level standard (SLS), defines a set of atmospheric conditions for physical calculations. The term "standard sea level" is used to indicate that values of properties are to be taken to be the same as those standard at sea level, and is done to define values for use in general calculations.
- Pressure, P = 101.325 kPa ⇔ 2116.2 lbf/ft2 ⇔ 14.696 lbf/in2
- Density, = 1.225 kg/m3 ⇔ 0.002377 slug/ft3
- Temperature, T = 15 °C ⇔ 288.15 K ⇔ 518.67 °R
- Gas constant of air, Rair = 287.057 J/(kg·K) ⇔ 1716.59 ft·lb/sl·°R)
- Specific Weight, = 12.014 N/m3 ⇔ 0.07647 lbf/ft3
- Dynamic viscosity, = 1.789×10−5 Pa·s ⇔ 3.737×10−7 slug/(s·ft)
- Acceleration of gravity, g0 = 9.807 m/s2 ⇔ 32.174 ft/s2
