Electronic Value Conversions

Hey, I'm just doing some Electronics homework and theres a couple of conversions that are confusing me a bit, and I am not sure whether I got the answer correct.

so what I have to do is convert the worded ammounts into something more appropriate, for example: 2000 Milli Amps = 2 Amps (getting rid of the unneccesary zeros).

Now onto my confusion:

300 Pico Volts + 1 Nano Volt. I got the answer 1nanovolt, which is somewhat confusing, did I do something wrong?

Re: Electronic Value Conversions

I do not agree, different names are 1000 times the other. Why not 1.3 nanovolts? Are you rounding?


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Electronic Value Conversions

hmm, my calculator may have rounded. I'll try with my pc calculator.

yeah, I think my calculator had some roundoff error, which is annoying to say the least, as doing the same operation on pc, I got the correct answer: 1.3 nanovolts.

Re: Electronic Value Conversions

Nine digits? Is it programmable?

Re: Electronic Value Conversions

I don't really know that much about it, when you say programmable, do you mean that you can change settings and modes (such as science mode, engineering modeetc) then yes.

If you mean programmable by the way you can add new functionality to it, then no.

But when it did the rounding error, I wasn't using the engineering mode.

also, it has a funky display style, google image it to see what I mean.

Re: Electronic Value Conversions

I think it is a nine digit job. Truth is you might be able to download a better scientific calculator from the net for free.

Re: Electronic Value Conversions

yeah, only problem is when I want to use it at school. It's not a huge problem, I'll prolly buy a Casio... which model do you recommend of the Casio brand?

Re: Electronic Value Conversions

Hi;

Actually I do not recommend any calculator. They are horribly overpriced and under featured. I have a a bunch of them sitting in a drawer gathering dust.

Re: Electronic Value Conversions

alright, I'll stick with this Sharp one that I already have, borrow others sitting around at home and use my pc calculator when needed.

Re: Electronic Value Conversions

That is certainly the most frugal idea.
