2 kilocalories in joule

NiftyRecipe converts 2 kilocalories to 8368 joule with a fixed SI-linked factor.

Kilojoules and megajoules describe energy on a scientific scale. The ratio applied here is 1 kilocalorie = 4184 joule, so this amount is 8368 joule. Reverse check: 1 joule ≈ 0.000239 kilocalorie. That helps when a lab notebook or spreadsheet only lists one column.
