About 1,012 M&M's chocolates fit in a quart jar.

A simple calculation can be done to estimate the number of chocolates that fit inside:

We know that the capacity of a quart jar is 946.352946 cubic centimeters (32 fl oz).

Determine the volume of a single M&M. In case you’re curious, average size is .636 cubic centimeters.

Calculate the percentage of the total volume the chocolates take up in the jar. Because of their unique shape, M&M’s poured randomly occupy 68% of the volume.

Divide your estimate for the size of a single M&M into 68% of the volume of the jar.

So that would be:

- 68% of 946.352946 = 643.52000328
- 643.52000328 /.636 = 1011.82390453
