Converting mV to Joules: How to Calculate?

AI Thread Summary
To convert millivolts (mV) to Joules using the conversion factor of 9.29 V/J, the correct approach involves first converting mV to volts. For a reading of 10 mV, this is done by dividing by 1000, resulting in 0.01 V. The conversion to Joules is then calculated by dividing the voltage in volts by the conversion factor, leading to the formula 0.01 V / 9.29 V/J. It's important to note that volts and joules measure different physical quantities; volts represent energy per unit charge, while joules measure energy. Understanding this distinction is crucial for accurate conversions.

I have a list of readings in mV and it says "The metre readings have a conversion factor of 9.29 V/J.

If there is a reading of 10 mV would you just do 10/9.29 to convert to Joules?

Thanks.

10mV is in miliVolts, or 10mV = (10/1000) V

So to convert 10mV into, let's call it Unit J (instead of Joules for a minute) (instead of mJ), using the given conversion, mathematically it's:

10mV = {{10mV \over 1000{mV \over V}} \over 9.29 {V \over J}}

(writing it out that way with is just to maybe help you see how the units work)

EDIT: But as an important note... Volts aren't the same as Joules
A Joule is a unit of energy, and 1 Volt is equal to 1 Joule of energy per Coulomb of charge, so V = J/C, in general. You can't convert from Volts to Joules, but you can convert from V to J/C, which is what I assume you are really doing, and the 9.29 has some unit related to charge.

I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks
Since ##px^9+q## is the factor, then ##x^9=\frac{-q}{p}## will be one of the roots. Let ##f(x)=27x^{18}+bx^9+70##, then: $$27\left(\frac{-q}{p}\right)^2+b\left(\frac{-q}{p}\right)+70=0$$ $$b=27 \frac{q}{p}+70 \frac{p}{q}$$ $$b=\frac{27q^2+70p^2}{pq}$$ From this expression, it looks like there is no greatest value of ##b## because increasing the value of ##p## and ##q## will also increase the value of ##b##. How to find the greatest value of ##b##? Thanks
