Octane is a hydrocarbon and an alkane with the chemical formula C8H18, and the condensed structural formula CH3(CH2)6CH3.

• 1 kg/m3 = 0.0624 lb/ft3
• 1 kJ/(kg K) = 0.2389 Btu/(lbm oF)
• 1 W/(m K) = 6.935 (Btu in)/(ft² h °F)
• 1 Pa s (N s/m2) = 10 P (Poise) = 103 cP = 0.1020 kp s/m2 = 0.6721 lb/(ft s)
