1 calorie in megajoule

NiftyRecipe converts 1 calorie to 0.000004 megajoule with a fixed SI-linked factor.

Kilojoules and megajoules describe energy on a scientific scale. The ratio applied here is 1 calorie = 0.000004 megajoule, so this amount is 0.000004 megajoule. Reverse check: 1 megajoule ≈ 239005.736138 calorie. That helps when a lab notebook or spreadsheet only lists one column.
