Length or Distance | fundamental | d | m (meter) | L (Length) |
Time | fundamental | t | s (second) | T (Time) |
Mass | fundamental | m | kg (kilogram) | M (Mass) |
Area | distance^{2} | A = d^{2} | m^{2} | L^{2} |
Volume | distance^{3} | V = d^{3} | m^{3} | L^{3} |
Density | mass / volume | d = m/V | kg/m^{3} | M/L^{3} |
Velocity | distance / time | v = d/t | m/s | L/T |
Acceleration | velocity / time | a = v/t | m/s^{2} | L/T^{2} |
Momentum | mass × velocity | p = m·v | kg·m/s | ML/T |
Force ( Weight) | mass × acceleration mass × acceleration of gravity | F = m·a W = m·g | N (newton) = kg·m/s^{2} | ML/T^{2} |
Pressure(Stress) | force / area | p = F/A | Pa (pascal) = N/m^{2} = kg/(m·s^{2}) | M/LT^{2} |
Energy or Work(Kinetic Energy /Potential Energy) | force × distance
mass × velocity^{2} / 2 mass × acceleration of gravity × height |
E = F·d KE = m·v^{2}/2 PE = m·g·h |
J (joule) = N·m = kg·m^{2}/s^{2} | ML^{2}/T^{2} |
Power | energy / time | P = E/t | W (watt) = J/s = kg·m^{2}/s^{3} | ML^{2}/T^{3} |
Impulse | force × time | I = F·t | N·s = kg·m/s | ML/T |
