English term

gigacalories

English Tech/Engineering Energy / Power Generation
Is there a way to convert a cost per gigacalorie of natural gas to a cost per cubic meter of same? I have a cost per gigacalorie and need to get it into a cost per US dollars of volume.

No fixed conversion! See explanation

Sorry, but I think there's no fixed conversion possible here! The energy content per cubic meter can vary, so there is no fixed calorie content. Natural gas prices for end users here in the Netherlands for example are per cubic meter, but are corrected for 'energy content'.

agree Kirill Semenov : sure, you can't convert energy into volume. It depends on the quality of the gas, I think

agree racedcadence : there is a way to get around this. the natural gas may vary by both gross and net calorific value, but there are conversion methods. i am trying to find the Groningen conversion factor at the moment. its a lower quality than north sea gas.

1 US$ / m3 = 107,5 US$ / Gc

pesar que medir por su volumen es útil, el gas natural se puede también medir como fuente de energía. Como otras formas de energía, el gas natural se mide y se expresa comúnmente en calorías. Una caloría es la cantidad de energía necesaria para calentar en un grado Celcius un gramo de agua, a presión ambiente y al nivel de mar (1 atmósfera). Un metro cúbico de gas natural contiene cerca de 9.300.000 calorías o 9.300 kilo calorías.

Así 1 m3 = 9300 Kc = 9,3 Mc = 9,3/1000 Gc
Por tanto, x US$ / m3 = x US$ /(9,3/1000 Gc)=
= x 1000/9,3 US$ / Gc = x 107,5 US$ / Gc

(sería bueno que algún ProZ revisase los cálculos)

As Arrabadan said this is relative. My example is for Chile, and approximate.

Here is a hypothetical answer

Using back of the envelope calculation I would say multiplying the cost of one gigacalorie of natural gas by 0.009082 will give you the cost per cubic metre of the same.

Here is the justification.

Assumption: One cubic metre of natural gas yields 38 MJ of energy or 38000000 joules.

(Source: http://en.wikipedia.org/wiki/Natural_gas#Energy_content)

One joule is approximately equal to 0.239 cal.

Therefore, one cubic metre of natural gas yields 38000000 x 0.239 calories.

Or, 9082000 cal.

Now you have the cost for 1 gigacalorie of natural gas. Let it be C.

Therefore, the cost for 9082000 calories of natural gas will be:

(9082000 x C)/1000000000 (1 gigacalorie = 1000000000 calorie)

= 0.009082 C
