Mathematical Conversions and Equations
STRESS EQUATION ---- 0.00689 N /mm² = 1 lb / in² OR 6895 N / m² = 1 lb / in²
HEAT TRANSMISSION EQUATION ---- 5.68 W / (m² • K°) = 1BTU / (ft² • hr • F°)
THERMAL CONDUCTIVITY (k): 1 W / (m • K) = 6.933 Btu • in
/ (ft² • hr • F°)
R VALUE (R): R = 1/k • thickness in inches
THERMAL CONDUCTIVITY EQUATION ---- 20.77 W / (m • K°) = BTU / (in • hr • F°)
TEMPERATURE CONVERSION ---- tc = 5/9 • (tf – 32) tf = 9/5 • tc + 32
DENSITY CONVERSION --- 16.02 Kg / m³ = 1 lb / ft³
