🇬🇧 Calibration meaning: English Vocabulary Flash Card

Calibration is the set of tiny lines and numbers on tools that measure things, like a ruler, thermometer, or weighing scale. These marks show you exactly how much, how long, how hot, or how heavy something is, so you don’t just guess. If the calibration is correct, your measurements are accurate, like knowing your temperature is 37°C and not secretly 370°C!
