What metric unit is commonly used to measure body temperature in many countries?

• A. Celsius (°C).
• B. Fahrenheit (°F).
• C. Kelvin (K).
• D. Rankine (R).

Answer: (A)

Measuring body temperature in Celsius is standard in many countries because it uses the metric system and keeps the normal human temperature range easy to interpret (around 37°C). Thermometers in most healthcare settings display temperatures in Celsius, and medical records are typically written in °C internationally. Fahrenheit is mainly used in the United States, so it isn’t as common elsewhere. Kelvin is a scientific scale for absolute temperature and isn’t practical for routine clinical readings. Rankine is rarely used in medicine. So, Celsius best fits global medical practice and everyday use.
