You can't. They are different units. It's like asking how many miles in a pint of milk.
Inches cubed x 16.387 = cm cubed
Multiply the cubic inches by 16387.064
Divide by 10^3
There are 10 mm in one cm. so one cm3 = 1000 mm3
25.3 cm (10 mm/1 cm) = 253 millimeters
Inches cubed x 16.387 = cm cubed
1 centimeters cubed = 1000 millimeters cubed
Multiply the cubic inches by 16387.064
Well you can't convert mL to cm, but you can convert mL to cm cubed. So 200 mL would be 200 cm cubed.
Divide by 10^3
1 cm cubed = 1 cm X 1 cm X 1 cm 1 cm = .01 m, so 1 cm cubed = .01 m X .01 m X .01 m Therefore, 1 cm cubed = .000001 m cubed, and 243 cm cubed = 243 X .000001 = .000243 m cubed. In summary, multiply cm cubed by .000001 to get m cubed.
There are 10 mm in one cm. so one cm3 = 1000 mm3
69 cm
25.3 cm (10 mm/1 cm) = 253 millimeters
1 ml = 1 cm3
cm measures length and cm cubed measures volume so you wouldn't convert one to the other. If you had a box you could measure the height, width and depth in cms and multiply all 3 to get the volume in cm cubed.
To convert centimeters into millimeters you need to know how that much one centimeter equals 10 millimeters. So you times the number of centimeters by ten to convert to millimeters. Here's an example: Convert 12 centimeters to millimeters. 12 cm x 10 mm/cm = 120 mm Note that our conversion factor is 10 millimeters per 1 centimeter, or 10 mm/cm. The cm units will "cancel out" and leave the answer in millimeters.
