Copyright © Ed2Net Learning, Inc.5 Degree of temperature. Degree Fahrenheit is a Customary unit of temperature. Degree Celsius is a metric unit of temperature.
Copyright © Ed2Net Learning, Inc.6 Negative number A number that is less than zero degree. Examples: -5 °C, -1 °C, -2 °C When temperature is very cold, the thermometers show numbers below zero or negative numbers.
Copyright © Ed2Net Learning, Inc.7 Thermometer A thermometer is used to measure temperature. It shows how warm or cold something is. Temperature can be measured in: Degree Celsius (°C) Degree Fahrenheit (°F)
Copyright © Ed2Net Learning, Inc.8 Important Tips The red line in thermometer is really a liquid. The liquid filled in thermometer is Mercury. It moves up when air is warm. It moves down when air is cool.
