k : kilo a SI prefix = 1000

kg (kilogram), the base unit of mass in the SI and MKS versions of the metric system. The kilogram is defined as the mass of the standard kilogram.
1 kg = 1000 g ~ 2.204 pounds

kg·m (kilogram metre)
1 : a metric unit of work or energy equal to 9.806 65 joules (J).
2 : a metric unit of torque equal to 9.806 65 newton metres (N·m).

kg·m/s (kilogram metre per second) = momentum.

kg·m/s2 (kilogram metre per second-squared) = force

kg·m2 (kilogram metre-squared) = moment of inertia

kg·m2/s2 (kilogram metre-squared per second-squared) = energy or work.

kg·m2/s3 (kilogram metre-squared per second-cubed) = power.

kg/m/s2 (kilogram per metre per second-squared), = pressure
See also the pascal.

kg/m3 (kilogram per metre-cubed) = densitymass density

kg/s (kilogram per second) = mass flow rate

kHz : kilohertz 1 kHz = 1000 Hz = 1000 Hertz.

kilo (k) an SI prefix = 103 • see other SI units

kilohertz (kHz) : 1000 Hz.


kilopascal (kPa), a common metric unit of pressure.

1 kilopascal = 1000 pascals (Pa) = 10 millibars (mb)


Kinematic Field Quantity

, acoustic examples, vibration velocity, particle velocity.

Kinetic Energy, all moving things have kinetic energy. It is energy possessed by an object due to its motion or movement, measured in joules.
