500 megajoules in joule

NiftyRecipe converts 500 megajoules to 500000000 joule with a fixed SI-linked factor.

Kilojoules and megajoules describe energy on a scientific scale. The ratio applied here is 1 megajoule = 1000000 joule, so this amount is 500000000 joule. Reverse check: 1 joule ≈ 0.000001 megajoule. That helps when a lab notebook or spreadsheet only lists one column.
