Kelvin

Kelvin is a unit of temperature measurement in the International System of Units (SI). It is named after the Scottish physicist William Thomson, 1st Baron Kelvin. The Kelvin scale is an absolute temperature scale, meaning it starts at absolute zero, the theoretical lowest possible temperature where the particles of matter have minimal motion.

Converting Celsius to Kelvin

The Kelvin scale is related to the Celsius scale by the following equation:

K = C + 273.15

Where K is the temperature in Kelvin, and C is the temperature in Celsius.

Converting Fahrenheit to Kelvin

The Kelvin scale can also be related to the Fahrenheit scale using the following equation:

K = (F - 32) × 5/9 + 273.15

Where K is the temperature in Kelvin, and F is the temperature in Fahrenheit.

Practice Problems

Convert 25°C to Kelvin.
Convert 68°F to Kelvin.
If the current temperature is 300K, what is the temperature in Celsius?
If the temperature is -10°C, what is the temperature in Kelvin?

With the understanding of these conversion formulas, you should be able to solve these practice problems. Good luck!

Connections to the Grade 5 Focal Points (NCTM)

Algebra: Students use patterns, models, and relationships as contexts for writing and solving simple equations and inequalities. They create graphs of simple equations. They explore prime and composite numbers and discover concepts related to the addition and subtraction of fractions as they use factors and multiples, including applications of common factors and common multiples. They develop an understanding of the order of operations and use it for all operations.
