measurement

Taking a measurement involves figuring out how long something is or what it weighs or how fast it is. Measurements usually require something like a ruler or a stop watch.

When you step on the scale to check your weight, you're getting a measurement. When you pull out a ruler and measure a piece of paper, you're making a measurement. Astronomers make measurements of how far away other planets and stars are. In the Olympics, a timer does a measurement of who's fastest, to see who won a race. Anytime you're using a measuring device to come up with a number for something, you're taking a measurement.
