Message	[ http://www.evanscooling.com/html/tech1.htm#ptbl1 ] There are a few ways to quantify specific heat. One is the number of joules it takes to heat one gram of material one degree celsius : water is 4.184 j/g C. Water is also considered to have a specific heat of 1.0 when you measure the specific heat with the number of BTUs it takes to heat one pound of material one degree fahrenheit: Water is 1.0 BTU/lb F. As quoted on their website, that fake coolant jizz (Evans NPG) is only 0.64 btu/lb F. To convert this to the j/g C measurement, you have to use a conversion. See below where X equals the specific heat of NPG Jizz. (4.184 j/g C)/(X j/g C) = (1.0 btu/lb F) / (0.64 btu/lb F) Then (4.184 j/g C)*(0.64 btu/lb F)/(X j/g C) = (1.0 btu/lb F) Then (4.184 j/g C)*(0.64 btu/lb F) = (1.0 btu/lb F)*(X j/g C) Then 2.67 j/g C = X j/g C Therefore X (specific heat of NGP jizz) is 2.67 j/g C.
