A SSL wasu kaddarorin yanayi sune: [2][3]
- Pressure, P = 101.325 kPa ⇔ 2116.2 lbf/ft2 ⇔ 14.696 lbf/in2 ⇔ 29.92 inHg
- 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
