Acceleration, Angular|0|18|Angular acceleration is the rate of change of angular velocity per unit time. See velocity/speed and time for more info. SI-derived unit: rad/s▓|-
Acceleration, linear|19|37|Linear acceleration is the rate of change of linear velocity per unit time. See velocity/speed and time for more info. SI-derived unit: m/s▓|-
Angle|38|56|Angle is the measure of arc between two planes. SI-unit: radian|-
Area|57|96|Area is the measure of the size of a surface. SI-unit: m▓|-
Computer|97|109|Computer sizes is the units computers are using. The prefixes are not the same. SI-derived unit: none|-
Conductance|110|114|No information yet. SI-derived unit: Siemen|-
Density, line|115|134|Line density is a measure of mass per unit length. The SI-derived unit of line density is kilograms/metre. A major use of line density is in the textile industry to indicate the coarseness of a yarn or fibre. For that purpose the SI unit is rather large so the preferred unit there is the tex. (1 tex = 1 gram/kilometre)|-
Density, volume|135|154|Density is the shortened term generally used in place of the more accurate description volumetric density.It is a measure of mass per unit volume. The S I compatible unit of density is kilograms/cubic metre. However, this a rather large unit for most purposes (iron is over 7000, wood is about 600 and even cork is over 200). A much more useful size of unit is g/cm│|-
Dynamic viscosity|155|167|Dynamic viscosity is the force of a fluid multiplied by the time per unit of area. The SI-derived unit is Pascal second|-
Electric current|168|177|Electric Current is the amount of electric charge flowing past a point per unit of time. The SI-derived unit is Ampere.|-
Electric induction|178|186|Electric induction is the creation of an electromotive force in a closed circuit by varying the magnetic field around the circuit. The SI-derived unit is Henry.|-
Electric resistance|187|195|Electric resistance is the reduction in the rate of current flow through a conductor.|-
Energy|196|217|Energy is the capacity of a physical system to do work. Kinetic energy is the capacity of matter to perform work as the result of motion. Potential energy is the capacity of matter to perform work as the result of position. There is a lot of room for confusion in some of the units used here. The calorie can take 5 different values and, while these do not vary by very much, for accurate work it is necessary to specify which calorie is being used.|-
Flow|218|241|Flow is the rate at which a volume quantity passes a specific point per unit of time. The SI-derived unit is m│/s|-
Force|242|253|Force is a vector quantity that produces the acceleration of a body in the same direction that the force was applied. The SI-derived unit is Newton|-
Illuminance|254|268|Illuminance is a measure of the intensity of light falling on a surface. The SI-derived unit is lux.|-
Kinematic Viscosity|269|276|No info yet.|-
Length|277|408|Length is a unit of measure used to estimate distances. The SI-unit of length is meter (or metre)|-
Magnetic Flux Density|409|434|Magnetic Flux Density is the amount of magnetic flux per unit area found perpendicular to the direction of the magnetic flux.|-
Mass|435|522|Mass is the measure of the quantity of matter an object contains. The mass of the body does not change with gravity and is not the same as, but is proporional to it's own weight. The SI-unit is kilogram.|-
Number|523|545|Numbers are a sort of prefixes which were commonly used many years ago. There is no SI-unit.|-
Power|546|566|Power is the time rate of doing work or the time rate of producing or expending energy. The SI-unit is Watt.|-
Pressure|567|598|Pressure is the force applied uniformly over a given area or foce per unit area.|-
Speed|599|618|Speed, or velocity, is a vector quantity of a body, with a magnitude of the body's speed an with direction of the body's direction of motion. The SI-derived unit is m/s.|-
Spread rate, mass|619|636|The spread rate of a substance is a measure of how much of it there is covering a unit area. The 'how much' can be measured by volume or by mass. The S I compatible unit of spread rate by mass is kilograms/square metre. It is also a measure of area density (mass/unit area) and is similar to - but not the same as - pressure, which is force/unit area. The SI-derived unit is kilogram/m▓.|-
Spread rate, volume|637|652|The spread rate of a substance is a measure of how much of it there is covering a unit area. The 'how much' can be measured by volume or by mass. The S I compatible unit of spread rate by volume is cubic metres/square metre. However, this is a rather large unit for most purposes and so litres/square metre is often preferred.|-
Temperature|653|657|Temperature is the degree of hotness or coldness of a body or environment. The SI-unit is Kelvin.|-
Time|658|673|Time is very abstract, and it's difficult to make a good description. The SI-unit is second.|-
Torque|674|686|Torque is the moment applied to an object that tends to make the object turn about it's axis of rotation. The SI-derived unit is Newton meter.|-
Volume|687|854|Volume, or capacity, is the amount of space occupied by a three-dimensional object. the SI-unit is cubic meter.|-
