Question

One litre is equal to —

• A. 100 millilitre
• B. 1000 millilitre
• C. 10 millilitre
• D. None of these

Hint:

Metric volume conversions: 1 litre = 1000 mL = 1000 cm³ 1 mL = 1 cm³ To convert litres to mL: multiply by 1000 To convert mL to litres: divide by 1000

Answer 1

The Correct Option is B

The litre is a unit of volume in the metric system. Understanding metric conversions is essential for measurements in daily life and science. Metric System Volume Conversions:

1 litre (L) = 1000 millilitres (mL)
1 millilitre = 0.001 litre
1 litre = 1000 cubic centimetres (cm³)
1 millilitre = 1 cubic centimetre (cm³)
Common Volume Equivalents: \begin{tabular}{|l|l|} \hline Unit & Equivalent
\hline 1 kilolitre (kL) & 1000 litres
1 litre (L) & 1000 millilitres
1 millilitre (mL) & 0.001 litre
1 millilitre & 1 cubic centimetre (cc/cm³)
\hline \end{tabular} Why 1000 Millilitre is Correct:

The metric system is based on powers of 10
"Milli-" means one-thousandth (1/1000)
Therefore, 1 litre = 1000 millilitres
Examples:

2 litres = 2000 mL
500 mL = 0.5 litre
250 mL = 0.25 litre (quarter litre)

Why Other Options are Incorrect:

(A) 100 millilitre: This is 0.1 litre (one-tenth of a litre), not one litre
(C) 10 millilitre: This is 0.01 litre (one-hundredth of a litre)
(D) None of these: Incorrect as 1000 mL is the correct equivalent
Final Answer: 1000 millilitre
