English/American Units pound mass (lbm)
meter (m)
foot or inch (ft or in) second (s)
current (I)
Ampere (A)

SI Units Newton (N)
English/American Units pound or ounce (lbf or oz)
Newton-meter (Nm) Joule (J)
foot-pound (ft-lb or in-lb) foot-pound (ft-lb or in-lb
Watt (W)
horsepower (hp or W) Volt (V) ohms (Ω)
kilogram-meter2 (kg-m2) radian (rad)
inch-pound-second2 (in-lb-s2) degree or radian (deg or rad) revolution (rev)
meter per sec. (m/s)
inch per second (in/s)
meter per second2 (m/s2) inch per second2 (in/s2) rad per second (rad/s)
velocity - rotational (ω) accel - angular (α)
rev per minute (rpm) rad per second2 (rad/s2)
Basic Definitions & Formulae Parameter Formula Force - accel (F = m * a) Torque - accel (T = J * α) Voltage, EMF (V = I * R) Work - Energy (E = F * L) Energy - elect (E = V * I * t) Power (P = F * v) Power (P = T * ω)
SI Units Formula
English/American Units Formula 2
1 N = 1 kg * 1 m / s 1 Nm = 1 kg-m2 * 1 rad / s2 1J=1N*1m
1 lbf = 1 lbf / (386 in / s2) * 386 in / s2 1 in-lb = 1 in-bl-s2 * 1 rad / s2 1V=1A*1Ω
1 in-lb = .113 Nm = .113 Ws = .113 J 1J=1V*1A*1s
1W=1N*1m/s 1 W = 1 Nm * 1 rad / s
1 hp = 550 ft-lb / s = 745.7 W (note: radians have no units)
Power (P = V * I) Power (P = E / t)
1W=1V*1A 1W=1J/1s
Power (P = I2 * R)
1 W = 1 A2 * 1 Ω
Motor Constants Parameter Formula Torque const (Kt = T / I)
SI Units Formula Kt = Nm / A
English/American Units Formula Kt = in-lb / A
Voltage const (Ke = V / ω)
Ke = V / (rad / s)
Ke = V / krpm
SI Units Formula 1 A = 1 Nm / (Nm / A)
English/American Units Formula 1 A = 1 in-lb / (in-lb / A)
1 V = AΩ + V / (rad / s) * (rad / s)
1 V = AΩ + V / (krpm) * (krpm)
Servo Motor Formulae Parameter Formula Current Draw (I + T / Kt) Voltage Required (V = IRa + Ke * ω)
Conversions:
To convert from units of A to units of B, find the value at the intersection of A and B, then multiply your number by this value. Example: to convert from cm to microns, multiply value in cm by 1.00E+04.
