Question

Convert the following $1c{{m}^{3}}=......ml$
A. 1
B. 10
C. 0.1
D. 100

Answer 1

Hint: One $c{{m}^{3}}$ of water has a mass of I gram which is equal to one $ml$.
Millilitre is the measure of water or any other liquid whose volume is equal to 1$c{{m}^{3}}$. It is already known that a millilitre is 1/1000 of a litre.

Complete answer:
First of all, convert from to $c{{m}^{3}}$ litres.
Litre is the standard metric unit of volume, used internationally everywhere. So it must be converted to one cubic centimetre to litres firstly. For a huge period of time, a litre is defined as the volume of one kilogram of freezing water which is measured at standard atmospheric pressure. But this definition has changed now to another one that is equivalent to a volume of exactly 1000 $c{{m}^{3}}$. Now the unit has been converted to $c{{m}^{3}}$. A conversion factor is a ratio that is helpful to convert from one set of units to an equal amount of different units. Next step is to convert litres to $ml$. This is the only step left to complete this question. It is already known that a millilitre is 1/1000 of a litre.

Additional Information:
The factor which is used to alter the units of a measured quantity without changing its actual value. Now let us check why unit conversion is important. Unit conversion is necessary because the other part of the world other than three countries generally uses the metric system. So, it is important to convert the equations for the internationalisation of science studies and to use metric systems.

Note:
So in short, unit conversion is step wise process that includes multiplication or division by a numerical factor then selection of the correct number of significant digits without any mistakes, and rounding also.
