Three approaches to mass and force units[1][2]
Base force, length, time weight, length, time mass, length, time
Force (F) F = ma = wa/g F = ma/gc = wa/g F = ma = wa/g
Weight (w) w = mg w = mg/gcm w = mg
Acceleration (a) ft/s2 m/s2 ft/s2 m/s2 ft/s2 Gal m/s2 m/s2
Mass (m) slug hyl lbm kg lb g t kg
Force (F) lb kp lbF kp pdl dyn sn N
Pressure (p) lb/in2 at PSI atm pdl/ft2 Ba pz Pa

The template table previously included rows that provided common labels or descriptions for the three approaches, as seen in this table. (Note that columns are not in the same order as in the template itself.) This was deemed inappropriate and should be discussed in surrounding prose where necessary.
