Differences for “ Weights And Measures ”

This page contains common units that my be useful when using the nutrient 
database.  
  
When measuring food, it is important to distinguish between weight(mass) and 
volume. Both are acceptable conventions of measuring food.  A conversion 
between weight and volume is not possible without knowing the density of food 
first.  For example, a cup of meringue and a cup corn meal can easily be 
measured, but the cups of those items won't weigh the same because their 
density is different. A meringue is much lighter than corn meal.  If 
measurements are not in volumes but in weights, then equal weights of something 
won't have the same volume unless they have the same density.  For example, a 
pound of meringue and a pound of corn meal both weigh the same, they're both a 
pound, but the volume, meaning the number of cups of each of those, will be 
different.  It takes far fewer cups of corn meal to reach a pound than it would 
of meringue.
