Temperature Conversion and Units

The video tutorial explains temperature units used in the US and Canada, focusing on Fahrenheit and Celsius. It introduces formulas for converting between Fahrenheit, Celsius, and Kelvin. The tutorial provides a step-by-step guide to calculate the temperature in Kelvin from a given Fahrenheit value, emphasizing the importance of not rounding intermediate results prematurely. The final result is rounded to the nearest whole number in Kelvin.

Which temperature unit is primarily used in the US?

• Rankine

• Fahrenheit

• Kelvin

• Celsius

What is the main temperature unit used in Canada?

• Rankine

• Celsius

• Kelvin

• Fahrenheit

What is the formula to convert Fahrenheit to Celsius?

• C = (F - 32) * 5/9

• C = F + 273.15

• C = F * 9/5 + 32

• C = F - 273.15

What is the relationship between Kelvin and Celsius?

• K = C + 32

• K = C + 273.15

• K = C - 273.15

• K = C * 9/5 + 32

If the temperature is 40°F, what is the first step to find the temperature in Celsius?

• Divide 40 by 5/9

• Multiply 40 by 9/5

• Subtract 32 from 40

• Add 273.15 to 40

After subtracting 32 from 40°F, what is the next step in converting to Celsius?

• Divide by 273.15

• Multiply by 9/5

• Add 273.15

• Multiply by 5/9

What is the approximate Celsius value when 40°F is converted?

• 7.77

• 6.66

• 5.55

• 4.44

What is the final step to convert Celsius to Kelvin?

• Multiply by 9/5

• Add 273.15

• Subtract 32

• Divide by 5/9

What is the Kelvin temperature when 4.44°C is converted?

• 278.00

• 279.15

• 280.00

• 277.59

What is the rounded Kelvin temperature for 40°F?

• 279

• 280

• 277

• 278
