That depends what units you are talking about.
Well, in the metric system, the base unit for distance is the meter. If that is the unit to which you refer, then there are 1000 milimeters in one "unit", or meter.
None. Watts is unit of power. Square meter is unit of area.
This question is nonsense. Gram is a weight unit and meter is a length unit. That cannot go together.
There is no such unit of measurement as the "pipe".
If you mean one aestronomical unit one astronomical unit (AU) , the answer is 150,000,000,000 meters.
A metre is a unit of distance. A square metre is a unit of area. The two units are therefore incompatible.
Gram is a unit of mass, meter is a unit for length !
Since a meter is a unit of length and a hectar is a unit of area, the two units are incompatible - you can't convert one to the other.
Meter is a unit of length. Milliliter is a unit of volume.
a quart is a unit of volume a metre is a unit of length the two are not compatible.
One Angstrom unit = 10^(-10) meter
One meter is equal to one million micrometers. Therefore, there are one million meters in a macro-meter.
