Does the USA still teach calories rather than Joules ?

Both can be found in most text books.

Dieters still count calories.

It is a lot easier for ME to remember that it takes one cal to raise one mL
of water one deg C than it would be to remember to use 4.187 Joules for the
same task.


Joules is now in use.

The calorie as is used in talk regarding dietary intake actually refers
to the kilocalorie.
