**kilogram (kg)**, 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

**kilogram metre (kg·m)**

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).

**kilogram metre squared per second cubed (kg·m**^{2}·s^{-3}),

power and the derived SI unit is the

watt (W), see

sound power.

**kilogram metre squared per second squared (kg·m**^{2}·s^{-2}), energy or work.

The derived SI unit is the

joule (J)

**kilogram metre per second (kg·m/s)** is the SI unit of

momentum. 1 kg·m/s = 1 N·s

**kilogram metre per second squared (kg·m/s²)**, a measurement of force

1 kg·m·s

^{-2} = 1 N = 10

^{5} dynes, the derived SI unit is the

newton

**kilogram per metre per second squared (kg/m/s²)**, a measurement of pressure

1 kg/m/s^{2} = 1 pascal (Pa) = 1 N/m^{2} = 1 J/m^{3} = 10^{-5} bar

pascal.

**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.
