It take 1 cal to raise 1 ml of water by 1 degree.
A watt is about 0.239 cal/second.

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.

So, how many PCBs do you think you have introduced into your body over
the years with all the various and sundry exposure events we Americans
have the opportunity to endure?

Amount needed to cause a malignancy mutation: 2 parts per Billion.

If you're willing to eat the crawfish, there's not a lot of point in
worrying about stuff leached off the drum. US cancer rates have been
gradually declining for decades, so we must be doing something right.

Are PCBs really carcinogenic? There are lots of references that say
not.

noting that PCB = polychlorinated biphenyl, not pc board

Joules is now in use.

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

Not used in Britain., although for some curious reason central heating boilers
and radiators continued to be specified in them until quite recently. Thankfully
they're in kW now.
