What on earth is a stick of butter?

What on earth is a stick of butter?

Many recipes online call for a stick of butter - in Canada we measure butter by the pound, the cup, the spoon - so it is confusing when a recipe calls for a stick.  The conversion equivalent is:

2 sticks of butter = 1 cup of butter

1 stick of butter = 1/2 cup of butter

1/2 stick of butter = 1/4 cup of butter

1 stick of butter = 1/4 pound

1 stick of butter = 8 tablespoons

1 stick of butter = 4 ounces

1 stick of butter = 113 grams

Can you even believe this one ???

I had no idea such a thing existed!!!

But very handy and quite brilliant just the same!!!
