Capacity facts for kids
Capacity is all about how much something can hold or do. It's like the maximum amount of space available in a container, or the biggest job someone or something can handle. Think of it as the "holding power" or "doing power" of something.
For example, a water bottle has a certain capacity, meaning it can only hold a specific amount of water. A stadium also has a capacity, which is the total number of people who can sit inside it.

Different Kinds of Capacity
The word "capacity" is used in many different ways across various subjects. Let's explore some of the most common ones.
Battery Capacity
When you talk about your phone or laptop, battery capacity tells you how much electrical energy its battery can store. This is usually measured in milliampere-hours (mAh) or watt-hours (Wh). A higher capacity means your device can run for longer before needing a recharge.
Carrying Capacity
In biology, carrying capacity refers to the largest number of living things (like animals or plants) that an environment can support over a long time. If a population grows beyond the carrying capacity, the environment might not have enough food, water, or space for everyone, which can lead to problems.
Heat Capacity
In physics, heat capacity measures how much heat energy a material can absorb before its temperature goes up. Materials with a high heat capacity, like water, can store a lot of heat without getting super hot. This is why water is often used in cooling systems.
Seating Capacity
Seating capacity is a simple idea: it's the total number of people who can sit in a place. This term is often used for sports stadiums, concert halls, theaters, or even buses and airplanes. For instance, a football stadium might have a seating capacity of 80,000, meaning 80,000 fans can watch the game there.
Economic Capacity
In economics, capacity can mean how much a business or a country can produce. If a factory has a high production capacity, it means it can make a lot of products. When a company uses most of its capacity, it's working efficiently.
Legal Capacity
Legal capacity is about a person's ability to do certain things legally. For example, to sign a contract or make important decisions, a person needs to have legal capacity. This usually means they are old enough and understand what they are doing.
Channel Capacity
In communication, channel capacity refers to the maximum amount of information that can be sent reliably through a communication channel. Think of it like the maximum speed limit on a data highway. A higher channel capacity means more data can be sent at once, like when you have a fast internet connection.
