    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:

    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.
