To convert Celsius to Fahrenheit, you can use the formula:

°F = (°C × 9/5) + 32.

For 20°C, you would substitute 20 into the formula:

°F = (20 × 9/5) + 32.

First, calculate 20 × 9/5, which equals 36. Then, add 32:

36 + 32 = 68°F.

Thus, the Fahrenheit equivalent of 20°C is correctly calculated to be 68°F. This temperature conversion is key in many scientific disciplines, including biomedical science, where accurate readings in temperature can significantly affect experiments, screenings, and patient care.
