According to "ASME Y14.36M-1996 Surface Texture Symbols" (only since I don't have a copy of the better reference, "ASME B46.1-2009 Surface Texture" handy), surface roughness (commonly called "surface finish" or "surface texture") is specified and measured either in micrometers (or microns) or microinches depending on the primary dimensional units of the drawing (which are typically specified in millimeters or inches). You may also see surface finish listed as "Ra" for average roughness. A micrometer (or micron) is one millionth (1/1,000,000) of a meter, and a microinch is one millionth of an inch. A value of 3.2 micrometers is considered equivalent to 125 microinches. More precisely, 1 microinch equals 0.0254 micrometers, or 1 micrometer equals 10.07874 microinches. Some examples, of typical roughness (or surface finish) values in microinches, with micrometer equivalents in brackets [], are 125 [3.2] (typical for milled or drilled surfaces), 63 [1.6] (typical for turned or reamed surfaces), 32 [0.80] (typical for ground surfaces), 16 [0.40] (typical for honed surfaces), or 8 [0.20] (typical for polished surfaces). All common average roughness (Ra) specifications, from roughest to smoothest, are listed below. 2000 [50] 1000 [25] 500 [12.5] 250 [6.3] 125 [3.2] 63 [1.6] 32 [0.80] 16 [0.40] 8 [0.20] 4 [0.10] 2 [0.05] 1 [0.025] .5 [0.012]
It is a micrometer, also called micron. It is 1 millionth of a meter. I hyphenated micrometer to differentiate the unit of measure from the measuring instrument.
No. You can take any unit of length to the third power (cube), but not to the second power (square), to get a volume. A square micrometer would be a unit of area.
Micrometer.
A micrometer is commonly known as a micron. It is an SI derived unit of length, which is equal to one millionth of a meter.

a micrometer
0.00001"
Microns, this is measured with a micrometer
By unit of length and distance and conversion ,we can say that 1 cm=10000 micrometer
1 micrometer = 0.001 millimeters. Google can be used for unit conversions.
Micrometer.
nope you have a micrometer and a nanometer
Yes, the definition of a derived unit is a combination of other units. Therefore, the following is not a single unit.AnswerNo. A micrometre is a submultiple (one-millionth) of a base unit: the metre.
