Re: What are Brittish Thermal Units ?

Hi Miler,

it is something you can use to measure energy - like, for example, joule or calories (you probably know it from food).

Take for example your body height - you can say that you are six foot tall or that you are about 1,80m tall. You have one thing you want to measure (lenght or height in this case) and have different systems to say "how much" you have, here the systems are feet and meters (or centimeters or inches or ... you can even invent your own units, "milers", if you want to and can say that it is 2.66 cm or whatever).

British Thermal Units are ebout the same as a joule - the energy you need to raise the temperature of one pound of water one degree F. But you can also say that you need 0.252 food calories or something else you can measure energy in!.
