You cannot use a measure of area to calculate its weight.
You need a third dimension to first calculate the volume and then convert to weight by knowing the density of the soil.
If you have a depth of one meter there is one cubic meter and soil has a density of about 1,3 so your cubic meter of soil weighs 1,3 tonnes.
Divide by 9.81
None. "square meter" is a unit of volume and "ton" is a unit of mass.
A tonne is a unit of mass; a square meter is a unit of area. You only "convert" units of the same kind.
3600 / 12 = 300 tons
1.69 tons
That would depend on what material you have a square meter of paper is going to be lighter than a square meter of rocks. Square meters don't just convert to tons you have to have a square meter of something
Divide by 9.81
Since 1 kilonewton equals 0.112 tons, 80 Kn is equal to 8.96 tons.
350 pounds per square foot equals 1.71 metric tons per square meter.
None. "square meter" is a unit of volume and "ton" is a unit of mass.
Of water one tonne
when convert from cubic meter to tonns multply by 0.455
If you harvest 3-4 kg per square meter you have 30-40 tons/harvest with good management in planting in soil and tuber fertilization.
A tonne is a unit of mass; a square meter is a unit of area. You only "convert" units of the same kind.
1/2 ton of refrigeration
3600 / 12 = 300 tons
2.2 tons
