Milligrams to calories Converter

Enter the milligrams, then press Calculate. The calories stay hidden while you type.

Press Calculate after the entries are in.

What this weight conversion is for

Use this page when a measurement is written in milligrams and the next step needs calories. The number stays blank until you press Calculate, so a half-typed entry is never mistaken for the answer.

The factor

This page uses the common diet estimate that one pound of body fat is about 3,500 dietary calories. 1 milligram = 0.00771618 calories. It is an energy estimate, not a scale conversion.

A worked example

10 milligrams are 0.07716179 calories. Multiply the result by the reverse factor if you want the original number back.

How to check it

Write the factor down, do the multiply on paper, and compare it with the result card. If you change a sentence on this page, edit the HTML file and reload. The form and this note live in the same file.

The reverse conversion is calories to milligrams. A nearby pair in the same units is milligrams to micrograms. When the converted number is the input to a job, continue with the calories to eat.
