Definitions for "K-Factor"
A measure of thermal conductivity or heat insulation. Lower values indicate a better insulating material.
Numerical representation of Thermal conductivity (See Thermal Conductivity).
K-value is a measure of a homogeneous material's ability to allow heat to pass through itself, independent of its thickness. If we multiply a material's C-value by its thickness, we have its K-value. [K = (BTU x °F)/(hr. x ft2 x in.)] Where BTU (British Thermal Unit) is the amount of heat required to raise the temperature of 1 lb. of water 1°F. K-factors are determined by either of two tests: ASTM C-177 or ASTM C-518
The strength constant in the formula for radial crushing strength of a plain sleeve specimen of sintered metal. See Radial Crushing Strength.
Constant factor, which is unique to each air diffuser design and model, used to figure the system airflow in calculations of HVAC. The information is available with the manufacturer of the diffuser.
A measurement that quantifies the effect of non-linear equipment, such as lighting ballasts, on an electrical system. Lighting systems should be designed so that the transformer rating is sufficient for the ballast used (typically K-factor 4). All OSRAM SYLVANIA ballasts meet this specification.
The proportion of daily traffic occurring during the peak hour, expressed as a decimal. For design purposes, K represents the proportion of AADT occurring during the thirtieth highest peak hour of the year.

In tropospheric radio propagation, the ratio of the effective Earth radius to the actual Earth radius.
Specific to each home. The number of degree days accumulated per gallon of fuel consumed. A good comparison is miles per gallon in an automobile.
An index representing the potential erodibility of a soil, by water based on soil texture.
