To convert a joule measurement to a calorie measurement, multiply the energy by the conversion ratio. The energy in calories is <b>equal to the joules multiplied by 0.239006<\/b>.<\/p>\n<h2>What is a calorie in joules?<\/h2>\n<p>The calorie was originally defined as the amount of heat required at a pressure of 1 standard atmosphere to raise the temperature of 1 gram of water 1\u00b0 Celsius.

In the equation PV=nRT, the term \u201cR\u201d stands for the <b>universal gas constant<\/b>.
