Question

What is 98.6°F and -5.00°F converted to Celsius and Kelvin?

Answer 1

`"98.6 °F = 37.0 °C = 310.2 K"`

`"-5.00 °F = -20.56 °C = 252.59 K"`

Explanation:

The formulas for temperature conversion are

`"C" = 5/9("F - 32")` and `"K = C + 273.15"`

1. Convert `"98.6 °F"`

`"C" = 5/9("F - 32") = 5/9(98.6 – 32) = 5/9 ×66.6 = "37.0 °C"`

`"K = C + 273.15 = 37.0 + 273.15 = 310.2 K"`

2. Convert `"-5.00 °F"`

`"C" = 5/9("F-32") = 5/9("-5.00 – 32") = 5/9("-37.00") = "-20.56 °C"`

`"K = C + 273.15 = -20.56 + 273.15 = 252.59 K"`

Note: The above formulas ignore units. With units, the formulas become

`"C" = "5 °C"/(9 color(red)(cancel(color(black)("°F"))))("-5.00 - 32") color(red)(cancel(color(black)("°F"))) = "-20.56 °C"`

and

`"K" = "-20.56" color(red)(cancel(color(black)("°C"))) × "1 K"/(1 color(red)(cancel(color(black)("°C")))) + "273.15 K = 252.59 K"`
