Thread: Measuring Energy

Hi, I have just started secondary school and for science homework have been asked to spend a short amount of time on the internet researching the old and new units for measuring energy along with the conversion factor. I have been looking on the web for a while now and think joules is the new unit but am struggling with the old unit. Any hints or tips would be great. I am keen to learn about science and really want to impress my teacher. Thank you.

I just did some work today with eV (Electron Volts) and Conversion into J (Jules) . To get an eV's value as a Jule, multiply the eV's value by 1.6x10^-19 will give you the value in Jules. If you want a Jules value in eV, then you divide the Jules value by 1.6x10^-19. Hope this helps ^^

Try this.
Conversion of units - Wikipedia, the free encyclopedia
The most common are foot-pound and BTUs, which are still used in the USA. Be careful with calories. A food Calorie is actually a kilocalorie.

There is a certain irony to that, and the USA's continued use of other "imperial" units.

A good app for conversions:

Convert for Windows - joshmadison.com

You can also use Google for converting units. For example, put 400 calories in btu or speed of light in furlongs per fortnight into Google and it will tell you.
