how do we convert centimeters cubed into millilters and liters and grams and kilograms?

thanks

this is in canadian

cm3 and milliliter are in fact the same. So 2500 cm3 = 2500 mL.

Prefix "milli" always means 0.001 for any unit. You can find

the list of metric prefixes handy. So 1 mL = 0.001 L, i.e. L = 1000 mL.

The same prefix rule works for grams and kilograms. Prefix "kilo" means 1000, so 1 kilogram = 1000 grams.

As for converting from liters/milliliters into grams/kilograms, there is no direct conversion since the former are units of volume and the latter are units of mass. Similar volumes of various substances may weigh differently. For example one liter of water is much lighter than one liter of mercury.
