Hey everyone,

Was just wondering if y'all could help me come up with some common physics unit values that would be good to memorize for the MCAT.
So far I have:

1 Watt/ = 1J/S = kg m^2 / s^3

1 N= 1 kg m / s^2

1 J = 1 N m = 1 kg m^2/ s^2

Hz = 1/ sec

Speed = m/s

Acc= m / s^2

1 C= 1 amp sec

1V= kg m^2/ s^3 A

1A= kg m^2 / s^3 A^2

Anything else I'm missing?? I'm tired of missing the unit conversion problems haha

Physics major here. Units will save you from remembering formulas, and formulas will save you from remembering units.

Here's an example:

So to do this I used the formulas that I knew (that you should know), that pressure is F/A. Which is N/m^2. What about J? Well it's energy, and energy can be Fdcostheta (work), or mgh (grav pot energy) or 1/2mv^2 (kinetic energy), all of these involve mass*acceleration*distance. I know from F = ma that mass*acceleration is Newtons. So Energy is just N*m.

So if m^3 is a L, then I know that J/L is just N*m / m^3 which is N/m^2 or pressure.

(I got the question wrong for misreading the kJ part, but I understand it aside from that)
