meters are a measure of lengthmeters squared are a measure of areaThey measure different things and cannot be directly converted.However, if you are given the lengths of, say, a rectangle, multiplying the two lengths (each measured in meters) together will find the area (measured in meters squared).
Conversion between the two units of measure is not possible because mph is a measure of speed, and m/s2 is a measure of acceleration, which is change in speed (or velocity).
Nothing. A squared metre is a measure of area. A kilogram is a measure of mass. The two measure entirely different things and it makes no sense at all to try to convert from one to the other.
None. A micrometre is a measure of length whereas a metre squared is a measure of area. The two have different dimensions and, as basic dimensional analysis will show, you cannot convert one to the other.
A nanometre is a measure of distance, metres per second is a measure of speed. The two measure different things and one cannot be converted to the other.
A square metre is a measure of area, with two dimensions, length and width [L2]. A metre is a measure of distance, with one dimension [L]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these.
None. A cubic metre is a measure of volume while a square metre is a measure of area. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
0.5 meter squared is not a measurement of length; it is a measurement of area. To find the length in meters, you would need to take the square root of 0.5 square meters, which is approximately 0.71 meters.
The SI unit is meters/second2 (meters/second/second). Any other unit of length divided by a time unit squared (or even a unit of length divided by two different time units) will do as well.
As squared meters are two-dimensional and cm are one- dimensional it is not possible. If you meant cm squared then: 1 Meter squared = 10000 Centimeter squared. Using this you can use simple multiplication to convert.
There are no kilometers in a second, as kilometers measure distance and seconds measure time.
20,000 square meters is two hectares.
