Useful LNG and Gas Conversion Factor


In this post, I want to share you a quite simple yet useful post, which is LNG conversion table. For your information, I have been working in several LNG regasification project, therefore this conversion is like my daily “menu”.

I hope you find this useful.

Conversion from tonnes LNG

tonnes LNG = 2.21 m3 LNG (liquid) (1)

tonnes LNG = 0.00127 m3 gas (n) (2)

tonnes LNG = 44.96 ft3 gas (n) (2)

tonnes LNG = 47.53 ft3 gas standard (scf) (3)

tonnes LNG = 51.02 MMBTU

Conversion from tonnes m3 LNG (liquid) (1)

m3 LNG (liquid) (1) = 0.45 tonnes LNG

m3 LNG (liquid) (1) = 571 m3 gas (n) (2)

m3 LNG (liquid) (1) = 20.17 ft3 gas (n) (2)

m3 LNG (liquid) (1) = 21.31 ft3 gas standard (scf) (3)

m3 LNG (liquid) (1) = 23.12 MMBTU

Conversion from m3 gas (n) (2)

m3 gas (n) (2) = 7.85 x 10-4 tonnes LNG

m3 gas (n) (2) = 1.75 x 10-3 m3 LNG (liquid) (1)

m3 gas (n) (2) = 3.53 x 10-2 ft3 gas (n) (2)

m3 gas (n) (2) = 3.73 x 10-2 ft3 gas standard (scf) (3)

m3 gas (n) (2) = 37.33 MMBTU

Conversion from ft3 gas (n) (2)

ft3 gas (n) (2) = 2.22 x 10-8 tonnes LNG

ft3 gas (n) (2) = 4.96 x 10-5 m3 LNG (liquid) (1)

ft3 gas (n) (2) = 2.83 x 10-2 m3 gas (n) (2)

ft3 gas (n) (2) = 1.05 ft3 gas standard (scf) (3)

ft3 gas (n) (2) = 1.15 x 10-3 MMBTU

Conversion from ft3 gas standard (scf) (3)

ft3 gas standard (scf) (3)= 2.10 x 10-8 tonnes LNG

ft3 gas standard (scf) (3) = 4.69 x 10-5 m3 LNG (liquid) (1)

ft3 gas standard (scf) (3) = 2.68 x 10-2 m3 gas (n) (2)

ft3 gas standard (scf) (3) = 0.948 ft3 gas (n) (2)

ft3 gas standard (scf) (3) = 1.09 x 10-3 MMBTU

Conversion from MMBTU

MMBTU = 1.96 x 10-2 tonnes LNG

MMBTU = 4.33 x 10-2 m3 LNG (liquid) (1)

MMBTU = 24.69 m3 gas (n) (2)

MMBTU = 872.2 ft3 gas (n) (2)

MMBTU = 920.1  ft3 gas standard (scf) (3)

Note:

(1) Calculated according to ISO 6579 (T = -160oC)

(2) Calculated according to ISO 6976 (0oC / 0oC, 1.01325 bar)

(3) Standard condition (15oC / 15oC, 1.01325 bar)
