4 kilocalories in megajoule

NiftyRecipe converts 4 kilocalories to 0.016736 megajoule with a fixed SI-linked factor.

Kilojoules and megajoules describe energy on a scientific scale. The ratio applied here is 1 kilocalorie = 0.004184 megajoule, so this amount is 0.016736 megajoule. Reverse check: 1 megajoule ≈ 239.005736 kilocalorie. That helps when a lab notebook or spreadsheet only lists one column.
