Converting Kelvin to Celsius: Key Techniques

Charlie Kov, a math teacher, explains how to convert Kelvin to Celsius. He emphasizes that 0° Kelvin is absolute zero, and negative Kelvin is not possible. To convert Kelvin to Celsius, subtract 273 from the Kelvin temperature. Unlike Fahrenheit, Celsius and Kelvin have the same degree size but start at different points. Examples are provided to illustrate the conversion process.

What is the value of absolute zero in Kelvin?

• 0 degrees Kelvin

• -273 degrees Celsius

• -100 degrees Celsius

• 100 degrees Kelvin

Why can't Kelvin have negative values?

• It's based on absolute zero

• It's always warmer than Celsius

• It's a law of physics

• It's a mathematical rule

How do you convert Kelvin to Celsius?

• Multiply by 273

• Subtract 273

• Add 273

• Divide by 273

What is 273 Kelvin in Celsius?

• 0 degrees Celsius

• 100 degrees Celsius

• -273 degrees Celsius

• 546 degrees Celsius

What is the equivalent of 373 Kelvin in Celsius?

• 100 degrees Celsius

• 0 degrees Celsius

• -200 degrees Celsius

• 646 degrees Celsius

How are Celsius and Kelvin scales similar?

• Both are used in the US

• Both measure heat only

• Both have the same degree increments

• Both start at zero for freezing
