I think this will come in handy for you.As you never know when you are asked to calculate the unit of a variable.
 
Here is the order
 
PQ:Physical quantities.
SI:SI Units.
DF:Dimensional formula. 
 
1.
PQ:Velocity = Displacement/Time
SI:m/s
DF:[M0L1T-1]
 
2.
PQ:Acceleration=Velocity/time
SI:m/s2
DF:[M0L1T-2]
 
3.
PQ:Force=mass*acceleration
SI:Kg-m/s2=Newton
DF:[MLT-2]
 
4.
PQ:Work=Force*Displacement
SI:Kg-m2/s2=N-m=Joule
DF:[ML2T-2]
 
5.
PQ:Energy

SI:radian
DF:[M0L0T0]
 
11.
PQ:Strain=dL/L or dV/V
SI:no units
DF:[M0L0T0]
 
12.
PQ:stress=Force*area
SI:N/m2
DF:[ML-1T-2]
 
13.
PQ:Pressure=Force*area
SI:N/m2

15.
PQ:Frequency=1/Time period
SI:Hz(Hertz)
DF:[M0L0T-1]
 
16.

Can one rememember all the formulae and can put it when asked without any mistake. NO doubt ur work is great.
But one must remember the formulae how it is derived.
