AI Thread Summary
The discussion revolves around the calculation of the unit 4.8912 × 10^12 m^2 kg/s^4, derived from multiplying hertz and watts. Participants clarify that this unit does not correspond to any known physical quantity, and it simplifies to Joules per second squared or Watts per second. The original poster intended to explore how far a photon could travel, but realized they lacked sufficient information for accurate calculations. It is noted that while dimensional analysis can yield interesting results, it may not provide definitive conclusions about physical phenomena. Ultimately, the conversation highlights the complexities and limitations of unit conversions in physics.

Change the forum if this is in the wrong place but I was doing some math (multiplying hertz and watts) and I came with 4.8912 × 10^12 m^2 kg / s^4, I don't know what unit that is, so can anybody tell me if there even is one?

there is no known physical quantity with those dimensions.

Watt = Joule/s = kg*m^2*s^{-3}

Hertz = s^{-1}

So your units are correct. Basically it's Joules per s^2, or Watts per second.

But as pointed out, it is unusual to multiply power and frequency. What was the calculation for?
 
I meant to divide hertz and watts and I would get 2 122.91667 m^-2 * kg^-1 * s^2 so now I think my question truly is what is that unit
 
As asked, what are you trying to accomplish? It almost seems like you are doing blind math, hoping to stumble on something interesting.

I was trying to find how far one photon can go like with a radio transmitter, how far could one of those photons could go. And now I found I did not have enough information to do these calculations.
 
There's no limit to how far a photon can go. But I'm not sure you can come to a conclusion like that by doing dimensional analysis. Sometimes interesting things can pop out though.
