Which is smaller Millileter or kiloleter?

Answer 1

A millilitre is one one thousandth of a litre, a kilolitre is one thousand litres, so one kilolitre is one million times larger than a millilitre.

Kilolitre isn't used really. The SI base unit of volume is the cubic metre, a cube one metre long, one metre wide, and one metre deep. A cubic metre is equal to one thousand litres. Litres tend to be used for fractions because as the metre is cubed the normal prefixes can be confusing.

1m3= 1 000 litres.

1dm3= 0.001m3=1 litre

1cm3= 0.000 001m3=0.001 litre = 1millilitre

1mm3= 0.000 000 001m3= 0.000 001 litre= 1 microlitre.

Litres tend to be used for volumes less than one cubic metre because the standard prefixes work better than they do for cubic metres, for multiples of cubic metres the standard prefixes aren't generally used, but volumes are expressed as thousands of cubic metres.
