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)

Good content, However some data also depend on its composition, i.e not every LNG had density 0.45 but as approximate is OK. you may know about lean LNG or Rich LNG. Also usually we used ratio 1:600 for volume of LNG when converted to gas (approximate) instead of 571. Another useful information like how much power 1 can generate for 1 m3 LNG , or how mu.ch duty required to vaporize 1 m3 LNG.
Thank you Pak Arief for leaving comment in my blog 🙂
m3 gas (n) (2) = 37.33 MMBTU, Is this correct? i thought 1 m^3 natural gas = 0.035315 mmbtu
Hello Anshuman,
I rechecked the source, 1 m3 gas = 33.73 MMBTU
Good info here capraenergy.com/ng-lng-unit-conversion-calculator/
LNG of various origins
Hi Adam,
Thank you for sharing the information 🙂
what would be the heat required to regasify say 1 m3 of LNG to gas
