Liquefied Natural Gas Energy Equivalent

Energy value of a liquefied natural gas depends on the source of the gas and he process that is used to liquefy the gas. We provide conversion for a typical energy value. The actual energy may vary up to 15%.

Higher heating value includes the energy of water vaporization. Lower heating value considers vapor not to be useful and does not count its energy.

Units: one kilogram of liquefied natural gas, higher heating value  / one kilogram of liquefied natural gas, lower heating value  / one pound of liquefied natural gas, higher heating value  / one pound of liquefied natural gas, lower heating value  / one liter of liquefied natural gas, higher heating value  / one liter of liquefied natural gas, lower heating value

Natural units

In physics, natural units are physical units of measurement based only on universal physical constants. The origin of their definition comes only from properties of nature and not from any human construct.

! The conversion is approximate.
Either the unit does not have an exact value,
or the exact value is unknown.
? Is it a number? Sorry, can't parse it. sorry (?) Sorry, we don't know this substance. Please pick one from the list. *** You have not choosen the substance. Please choose one.
Without the substance conversion to some units cannot be calculated.

Hint: Can't figure out where to look for your unit? Try searching for the unit name. The search box is in the top right corner of the page.
Has convert-me.com really existed since 1996? In fact it's even older. We launched the first version of our online units converter in 1995. There was no JavaScript there and all conversions had to be done on server. The service was slow. A year later the technology allowed us to create an instant units conversion service that became the prototype of what you see now.
To conserve space on the page some units block may display collapsed. Tap any unit block header to expand/collapse it.
Does the page look too crowded with so many units? You can hide the blocks you don't need by clicking on the block headline. Try it. Clicking again will expand the block.
Our goal is to make units conversion as easy as possible. Got ideas how to make it better? Let us know.
