125 joules in megajoule

NiftyRecipe converts 125 joules to 0.000125 megajoule with a fixed SI-linked factor.

Kilojoules and megajoules describe energy on a scientific scale. The ratio applied here is 1 joule = 0.000001 megajoule, so this amount is 0.000125 megajoule. Reverse check: 1 megajoule ≈ 1000000 joule. That helps when a lab notebook or spreadsheet only lists one column.
