Count
A measure that involves countable amounts (?eaches? as well as cases, etc.). Can be decimal.
NOTE: Count is not disjoint with all the other magnitudes, as there are some magnitudes that could conceivably be counted.
Electric Current
A flow of electric charge.
Information Quantity
An amount of data, such as 6 petabytes, or 640KB.
Luminous Intensity
A measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle. This is based on the luminosity function, a standardized model of the sensitivity of the human eye.
Molar Quantity
Amount of a substance, as counted molecules.
Monetary
A special type of magnitude, due to the way rounding is handled in math and the temporal aspect of conversion.
Percentage
A ratio where the numerator and denominator are of the same unit of measure.
NOTE: there are various ways to represent percentage: 50/100 could be represented as ?50? or ?0.5?. gist uses the latter, as it involves fewer conversions for subsequent use.
Product Magnitude
A magnitude expressed as a product of primitives. (E.g., Force = M*A).
Ratio Magnitude
EXAMPLE: Speed. The ratio magnitude is 60, the unit of measure might be MilesPerHour.
NOTE: A RatioMagnitude just has one decimal value.
This is a number whose unit of measure is a ratio.
Temperature
The degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale.
