-5°F to kelvins nearest whole number

252

Explanation:

# turn F to C

C=(F-32)5/9

C=(-5-32)5/9

C=-37 × (5/9)

C= -21

# turn C to K

K=C+273

K=(-21)+273

K=252

253 Kelvins

Explanation:

We want to convert -5°F to Kelvins.

First, we must convert -5°F to Celsius. The formula is:

°C= (°F - 32) * 5/9

Plug -5 in for °F.

°C= (-5-32) * 5/9

Solve inside the parentheses first. Subtract 32 from -5.

°C= (-37) * 5/9

Multiply -37 and 5/9.

°C= -20.5555556

-5° F is equal to -20.5555556° C.

Next, convert Celsius to Kelvins. The formula is:

K= °C + 273.15

Plug -20.5555556 in for °C.

K= -20.5555556 + 273.15

Add -20.5555556 and 273.15.

K= 252.594444

Round to the nearest whole number. The 5 in the tenth place tells us to round 252 to 253.

K ≈ 253

-5°F is equal to about 253 Kelvins.
