Final answer:
The record high temperature in Ohio of 113°F is equivalent to 45°C when converted using the temperature conversion formula.
Step-by-step explanation:
The record high temperature in Ohio is 113 degrees Fahrenheit, and to convert this to Celsius, we need to use the following formula: Tc = (5/9) * (T.f - 32), where Tc is the temperature in Celsius and T.f is the temperature in Fahrenheit.
Substituting the given temperature:
Tc = (5/9) * (113 - 32)
Tc = (5/9) * 81
Tc = 45
Therefore, the record high temperature in Ohio in degrees Celsius is 45°C.
