Measurement

Measurement is a way of counting. It's how people compare things like size and weight. We use measuring tools like rulers, scales, and thermometers to measure different things. A ruler is used to measure length, or how long something is. A scale is used to measure weight, or how heavy something is. A thermometer is used to measure temperature, or how hot or cold something is. Measurement helps us compare things to each other and make sure things are the right size or weight.
