The multiplicative factor for converting a unit into International System of Units (SI) units. The factor is expressed in the form number > x, where number is a numerical value and x is the appropriate SI units. The basic SI units are Enumerated: m (meter), N (newton), kg (kilogram), Pa (pascal), s (second), Hz (hertz), A (ampere), V (volt), K (kelvin), W (watt), rad (radian), J (joule), sr (steradian), C (coulomb), T (tesla), ohm (ohm), mho (mho or seimens), H (henry), and F (farad). Two useful units which are not SI units are: degree (angle), and unitless (no units). An example is: 1.0E-5>T which converts the units, presumable nT, to tesla. Another example is: 1.0e-1>km/s which converts a velocity expressed in meters per second to kilometers per second.
