## K : Sound and Vibration Terms and Definitions ...

**k : kilo** an 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/s**^{3} : kilogram metre-squared per second-cubed =

power.

**kg/m/s² : kilogram per metre per second-squared**, =

pressure

pascal.

**kg/m**^{3} : kilogram per metre-cubed =

density •

mass density

**kg/s : kilogram per second** =

mass flow rate

**kHz : kilohertz** 1 kHz = 1000 Hz = 1000

Hertz.

**kilo (k)** an SI prefix = 10

^{3} • see other

SI units

**kilohertz (kHz)** : 1000 Hz.

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

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

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