It can be used to indicate a smaller than average scale (microscopic scale), as opposed to prefixes mega and macro, which can be used to indicate a larger than average scale. Micro may refer to: 1  micro- (Âµ) a prefix in the SI and other systems of units denoting a factor of 10 â6 (one millionth). 2  MICRO Information Management System, an early set-theoretic database management system. 3  Micro programming language, a simple programming language used in teaching compiler construction techniques.
The divisions are tracked by the prefix. In this case milli means [math]1/1,000[/math] of the original unit (divided by 10 three times). Similarly micro means [math]1/1,000,000[/math] of the original unit (divided by 10 six times). This said, for the milliamp [math]1 mA = 0.001 A[/math] and for the microamp [math]1 \mu A = 0.000001A[/math] then the milliamp is one thousandfold bigger than the microamp. For this reason there are 1000 microamps in a milliamp, or [math]1000\mu A = 1mA[/math].
