Common Dimensional Formulae:

• Force: [$MLT^{-2}$], Energy: [ML^{2T}^{-2}], Power: [ML^{2T}^{-3}]
• Pressure: [ML^{-1}$$T^{-2}], Momentum: [$MLT^{-1}$]
• Planck's constant: [ML^{2T}^{-1}], G: [M^{-1}$$L^{3T}^{-2}]

Error Propagation:

• Z = A +/- B: Delta(Z) = Delta(A) + Delta(B)
• Z = A * B or A/B: Delta$\frac{Z}{Z}$ = Delta$\frac{A}{A}$ + Delta$\frac{B}{B}$
• Z = $A^n$: Delta$\frac{Z}{Z}$ = |n| * Delta$\frac{A}{A}$
• Z = $A^p$ * $B^q$ / $C^r$: Delta$\frac{Z}{Z}$ = |p|*Delta$\frac{A}{A}$ + |q|*Delta$\frac{B}{B}$ + |r|*Delta$\frac{C}{C}$

Unit Conversion: $n_2$ = $n_1$ * $\frac{M_1}{M_2}$^a * $\frac{L_1}{L_2}$^b * $\frac{T_1}{T_2}$^c

Instruments:

• Vernier LC = 1 MSD - 1 VSD
• Screw gauge LC = Pitch / Circular divisions
