100,000 B.T.U. = 105.5 Mj.
100,000 B.T.U. = 1 THERM
21.5 THERM = 630 KW Hrs.
1 B.T.U. = 1.055 Kj.
3,412 B.T.U. = 1 KW
1000 B.T.U. = 1.055 Mj./Hr.
24,350 B.T.U. = 1.1 lb
948.123 B.T.U. = 1Mj.
1 LITRE = 24,350 B.T.U. = 1.1 lb
1 LITRE = 25.4 Mj.
1 LITRE = 6.93 Kw Hrs.
2 LITRE = 1 Kg. Wt. Approx.
1 Kg. = 50.4 Mj.
1 Kg. = 47,000 B.T.U. Vapourised
1.055 Mj./Hr. = 948.213 B.T.U.

1 Kg. = 47,000 B.T.U. Vapourised

1 MPa = 10 BAR = 1000 KPa = 145.03 psi = 10.19 KG/sq.CM

100 psi = 690 KPa = .69 MPa = 6.9 BAR = 7.03 KG/sq.CM

1 BAR= 100 KPa = 14.5 psi = 1.02 KG/sq.CM = .1 MPa

1 KG/sq.CM = 14.2 psi = .98 BAR = 98 KPa = .098 MPa
