Grams per square metre is a measure of planar density while a millimetre is a measure of distance (or length). The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
There are 300 grams per square meter, which means there are 300 grams spread over an area of one square meter. To convert this to millimeters, you would need to know the thickness or height of the material in question (e.g. paper, fabric) to calculate how many millimeters this weight would cover.
How many millimeters are in a meter? There are 1000 millimeters in a meter.
There are 1000 millimeters in a meter.
There are 1,000,000 square millimeters in one square meter. This is because a square meter is equivalent to 1,000 millimeters in length and 1,000 millimeters in width. Multiplying these dimensions gives 1,000 x 1,000 = 1,000,000 square millimeters.
1 meter = 1000 millimeters 1 millimeter = 0.001 meter
1 meter = 1000 millimeters 1 millimeter = 0.001 meter
1000000 square millimeters fill 1 square meter.
Since each meter has 1000 millimeters, each square meter has a million square millimeters.
1 square meter is made up of 1,000,000 square millimeters. This can be figured out because if there are 1,000 millimeters in one meter, then there would be 1,000,000 square millimeters in one square meter.
1 square meter = 1 million square millimeters
Since one meter has 1000 millimeters, a square meter has 1000 x 1000 = a million square millimeters.
100,000
One square meter equals 1 million square millimeters.

1 meter=1,000,000 millimeters.
Doesn't work. Square millimeters is a unit for area, while meter is a unit for distance only. They don't compare. You might as well ask about how fast a pound is.
