Final answer:
The average temperature of healthy humans on the Celsius scale is 37°C, representing the normal body temperature.
Step-by-step explanation:
The average temperature of healthy humans on the Celsius scale is 37°C. This temperature is considered the normal body temperature and is often used as a reference point in medicine. However, it's important to note that actual body temperature can vary slightly depending on the time of day, the method of measurement, and among different individuals. While variations exist, the normal range is typically between 36.5°C to 37.5°C (97.7°F to 99.5°F), and anything outside this range could potentially indicate a medical concern, such as a fever or hypothermia.
