Volume measurements are crucial for quantifying the space that an object occupies or the capacity of containers. Metric units provide a standardized way to measure volume.
Liter: The liter is the standard metric unit for volume. It is commonly used to measure liquids, such as beverages and fuel. For example, a bottle of soda or a gallon of milk is often described in liters.
Milliliter: A milliliter is a smaller unit of volume, frequently used in cooking and medicine. It is ideal for measuring small quantities, such as medication doses or ingredients in a recipe.

2.2 Imperial Units

In countries that use imperial units, different measurements are employed for liquid volume.
Gallon: The gallon is a larger unit used for measuring liquid volumes. It is commonly used in the US to describe quantities of gasoline or milk. There are different gallon measurements, such as the US gallon and the UK gallon.
Quart: A quart is equal to ¼ gallon, often used for liquids like milk or oil. It is a convenient unit for measuring moderate quantities.
Pint: Half of a quart, the pint is used for various liquid measurements, such as in the food and beverage industry. Pints are commonly used to measure beer or milk.
Fluid Ounce: The fluid ounce is a smaller unit for liquid volume, often used in cooking and beverage measurements. It is especially useful for precise measurements in recipes.

3. Units of Weight

3.1 Metric Units

Weight measurements help us determine how heavy an object is, and different units are used across systems.
Gram: The gram is the basic unit of mass in the metric system. It is used globally to measure lightweight objects, such as ingredients in recipes or small packages.
Kilogram: A kilogram is a larger unit of mass, used for heavier objects. It is commonly used to measure body weight, groceries, and larger items.

3.2 Imperial Units

Imperial units are also used for weight measurements, particularly in the US.
Ounce: The ounce is a small unit of weight, used for measuring lighter objects. It is commonly used in food packaging and cooking.
Pound: Equal to 16 ounces, the pound is used for heavier items. It is a standard unit for measuring body weight, produce, and other goods.

4. Units of Energy and Power

4.1 Energy

Measuring energy is crucial for understanding various physical phenomena and technological processes.
