A Few Conversion Factors
1 Lb/IN^2 = 2.31 FT water at 60 degrees F
= 2.04 IN.HG at 60 degrees F
1 FT.Water 60 F = .433 LB/IN^2
= .884 IN.HG at 60 F
1 IN.HG @ 60 F = .49 LB/IN^2
= 1.13 FT Water at 60 F
1 FT = .3048 M 1 YD^2 = .8361 M^2
1 FT^2 = .0929 M^2 1 YD^3 = .7645 M^3
1 IN. = 2.54 CM
1 FL GAL = 4.5459 LITERS
1 DEGREE F = (1.8 * Temp C ) + 32
1 DEGREE C = (Temp F - 32) / 1.8
1 LB = .4536 KG
1 OZ = 28.3495 GRAMS
1 OZ/YD 2 = 305.16 G/M^2
1 LBF = 4.4482 N
1 LBF/IN^2 = .0703 GKF/CM^2 = 6.8948 kN/M^2
1 LB/FT^3 = 16.018 KG/M^3
1 LB/IN^3 = 27.68 G/CM^3
1 KGF/CM 2 = 14.2233 LBF/IN^2 = 98.0665 kN/M^2
1 BAR = .1 MPA = .1 N/MM^2 = 14.5036 LBF/IN^2
1 GPM = .134 FT 3/MIN.
1 FT 3/MIN. = 448.8 GAL/HR
Weight of water: 1 FT^3 = 62.41 LB @ 50 Degrees F
1 GAL = 8.34 LB @ 50 F
1 FT 3 of Ice = 57.2 LB
Water = Greatest Density @ 39.2F
1 FT^3 = 62.43 @ 39.2F
