A lot.
There is 1000 in the difference between a metre and a kilometre. Then this figure is cubed, it becomes 1 billion (1,000,000,000 metres cubed).
A metre cubed is 1000 litres.
So there are 1,000,000,000,000 litres in a cubic kilometer.
There are zero cubic metres in any number of square kilometres; any two-dimensional area has zero volume.
There are 1 million square meters in 1 square kilometre.
There are 1 billion cubic meters in 1 cubic kilometre.
Well approaching the problem from the other end, there are 1000 x 1000 x 1000 cubic metres in 1 cubic kilometre. i.e 109.
So a cubic kilometre will be 10-9 of a cubic metre. i.e. 0.000 000 0001.
One cubic kilometer equates to 1 billion (1,000,000,000) cubic meters.
one billion because 1000 m = 1 km so there are 10003 = 1 billion meters cubed in a kilometer cubed.
1 cubic meter equates to 100,000 centiliters.
One cubic meter = 1,000 liters.
There are 35.3 (35.3146667) cubic feet in one cubic meter.
One cubic meter equates to 61,023.74 cubic inches.
There are 1003 , or 1000000 cubic cm in one cubic meter.
1 cubic meter is about 35.3 cubic feet.
There are 35.3147 cubic feet in 1 cubic meter.
One cubic meter is equal to 264.17205 US gallons.
one thousandth cubic meter (1 cubic meter = 1000 cubic liter)
1,000 liters per cubic meter.
There are 264.2 US gallons in one cubic meter.
1,000 liters per cubic meter.
1 liter = 0.001 cubic meter 1 cubic meter = 1,000 liters
