## K : Sound and Vibration Terms, Definitions, Units, Measurements ...

**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
See also the

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.
