Session 10: Temperature Conversion – Metric Units and Customary Units
Admin 17/11/2024
Measurement is a concept that appears all the time in everyday life. To measure something is to determine the size, amount, or degree of a quantity or object, using standard or non-standard units. Measurements can be made of physical quantities such as length, mass, time, temperature, electric current, and luminous intensity, among others.
Measurement of Temperature
Temperature is the measurement of the degree of hotness or coldness of an object or environment. Temperature is commonly measured using a thermometer, which can be in the form of a mercury or digital thermometer. Some of the units of temperature are Fahrenheit, Celsius, and Kelvin. These units can be converted between one another.
Temperature Conversion
Converting temperatures from one unit to another is known as temperature conversion. For instance, Fahrenheit can be converted to Celsius, and Celsius can be converted to Kelvin.
In our daily lives, we encounter numerous values of temperature, such as the temperature of the air outside, the temperature of the water in a swimming pool, or the temperature of an oven while baking.
In the metric system, the unit of temperature is the degree Celsius (°C), which is based on the freezing and boiling points of water. The Celsius scale sets the freezing point of water at 0°C and the boiling point at 100°C, with the range between these two points divided into 100 equal parts or degrees.
| DID YOU KNOW? In 1742, Swedish astronomer Anders Celsius created a temperature scale that we use today for temperature measurement. He used 0° for the boiling point and 100° for the freezing point of water to avoid negative numbers. This was later inverted to put 0° on the cold end and 100° on the hot end, and it is in this form, it continues to be used today. Since 1948, it has been most commonly referred to as the Celsius scale in honour of its originator. |
Temperature Conversion in Metric Measurement System
The Metric Measurement System, also known as the International System of Units (SI), is a globally recognized and standardized system of measurements that simplifies and unifies the units of length, mass, and capacity, as well as temperature. The system is based on the metre, kilogram, second, ampere, kelvin, mole, and candela as the fundamental units of length, mass, time, electric current, temperature, amount of substance, and luminous intensity, respectively.
In the metric system, the base unit of temperature is the Kelvin (K), which is defined as 1/273.16 of the thermodynamic temperature of the triple point of water.
Temperature Conversion in Customary Measurement System
The United States does not officially use the SI system. They follow their own measurement system called the United States Customary Measurement System. The customary units of temperature are based on the Fahrenheit scale.
