For faster calculations, the memorization of these conversion factors will aid calculations in Chemical Engineering analyses.
1
Q
1 J to BTU
A
1 J = 1055 BTU
2
Q
1 atm to Pa
A
1 atm = 101325 Pa
3
Q
1 atm to psia
A
1 atm = 14.7 psia
4
Q
psig to psia
A
psia = psig + 14.7
5
Q
psiv to psia
A
psia = 14.7 - psiv
6
Q
°C to °F
A
°F = (9/5) × °C + 32
°F is always greater than °C, hence slope should be > 1 which is 9/5.
7
Q
°F to °C
A
°C = (°F - 32)(5/9)
°C is always less than °F, hence slope should be < 1 which is 5/9.
8
Q
°C to K
A
K = °C + 273.15
9
Q
°F to °R
A
°R ≅ °F + 460
Exactly 0°F = 459.67°R
10
Q
1 ft³ to gal
A
1 ft³ = 7.48 gal
11
Q
1 lb = g
A
1 lb = 454 g
Similar to lbmol = mol
