Converting from mm to metres cubed.

If I have an answer of 35,700,000mm cubed how do I convert this to metres cubed. I have worked out the answer a different way to get 0.357metres. What is the formula for converting this from mm to centimetres cubed and then metres cubed? I would be grateful for an explanation.

Jim

there are 1,000 cubic millimeters in 1 cubic centimeter
there are 1,000,000 cubic centimeters in 1 cubic meter

I hope this helps
if you look on the home page there is a conversion table

Re: Converting from mm to metres cubed.

I did forget that you wanted a formula.

length times width equals square times height equals cubic.

L * W = Square
L * W * H = cubic

to go back if all sides were equal you could use square root from cubic to square and square root again to get back to length or width.
I think you were off on your answer. I didn't work it out but I think there is a zero needed on the right hand side of the decimal point.

Re: Converting from mm to metres cubed.

Hi Jim and Sandra,

There is 1000millimeters in a meter.
There is 100centimeters in a meter.

This means that a cube shaped object with all its sides 1 meter in length is
1 cubic meter, or

100x100x100cm = 1,000,000 cubic centimeters

1000x1000x1000mm = 1,000,000,000 cubic millimeters.

35,700,000 ÷ 1,000,000,000 = 0.0357m³

(There is 10mm in 1cm)

1 m^3 = 10^9 mm^3

we're thinking in the third dimension baby

Two ways:
a) Multiply the millimeters and divide by 10^9 (it's 1000 mm/m, cubed)
b) Convert to meters and multiply, 0.8 x 1.2 x 1.2 = 1.152m³
The two ways give the same answer, I find "b" easier, but up to you.

20 L = 20 dm³ or 20000 cm³

For a cylinder, V = (pi/4)*D²*L
L = (4/pi)*V/D² = 1.2732 x 20000 cm³/(45 cm)² = 9.88 cm

That would be the fill level, the container should be a little taller to allow headspace for thermal expansion.
