Eggs: Measuring One Cup
To measure a cup of whole egg, egg whites, or egg yolks, use the following chart:
| Size | Whole | Whites | Yolks |
| Jumbo | 4 | .5 | .11 |
| X-Large | 4 | .6 | .12 |
| Large | 5 | .7 | .14 |
| Medium | 5 | .8 | .16 |
| Small | 6 | .9 | .18 |
For example, it takes 5 whole medium-sized eggs to make a cup, the whites of 8 medium-sized eggs to make a cup, and the yolks of 16 medium-sized eggs to make a cup.
