AI Thread Summary
To convert MeV/cm^3 to rads, it's important to note that MeV/cm^3 cannot be directly converted to rads or Grays due to dimensional differences. Rads measure absorbed radiation per mass, while MeV/cm^3 measures absorbed radiation per volume. The correct approach involves converting MeV/cm^3 to Grays, which requires knowing the density of the material in question. Grays (Gy) are related to rads, with 1 Gy equal to 100 rads. Understanding these units is crucial for accurate radiation dose calculations.

Convert MeV/cm^3 to rads

I wish I knew..


The Attempt at a Solution



I tried looking up the unit conversions, but find nothing that connects them, I know rads is connected to the Gray which is J/Kg but can't connect it to the MeV/cm^3. Any ideas?

Hi ~Sam~! :smile:

rad is the old cgs unit, gray (small "g") or Gy (= 100 rad) is the SI unit … see http://en.wikipedia.org/wiki/Gray_(unit)"

MeV/cm3 has the wrong dimensions, so you can't convert it to rad or Gy …

MeV/cm3 would convert to Gy times density (J/kg times kg/m3) :wink:

Gy measures absorbed radiation per mass, MeV/cm3 measures absorbed radiation per volume

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
