A centilitre (cl) is a metric unit of volume that is equal to one-hundredth of a litre. It is commonly used in measuring liquids, especially in cooking and beverage industries. For example, a standard bottle of wine may contain 750 centilitres, which is equivalent to 75 centilitres. The centilitre is part of the metric system, which is widely used around the world for scientific and everyday measurements. It is useful for precise measurements in recipes and nutritional information, making it easier to understand portion sizes and serving amounts in relation to litres and millilitres.
