Medical Relevance of Temperature

Core temperature

The temperature of the deep tissues of the body—the “core” of the body—remains almost exactly constant, within ±1°F (±0.6°C), day in and day out except when a person febrile illness.

Normal core temperature

The average normal core temperature is generally considered to be between 98.0° and 98.6°F when measured orally and about 1°F higher when measured rectally.

Hyperpyrexia

Occurs between 105—108°F. Circulatory shock, cell destruction and organ failure are followed by death.

Hypothermia

Occurs between 94—77°F. Once the core temperature falls below 85°F temperature regulation is lost. Death by cardiac arrest or ventricular fibrillation occurs once body temperature falls to 77°F.

Temperature Assessment Sites

Various sites such as Pulmonary artery (most accurate), Esophageal, Bladder, Rectal, Tympanic, Oral, Axillary and Forehead (least accurate)

Assessment SitesTemperature in Celsius (C°) & Fahrenheit (F°)
Oral37 Celsius which is equal to 98.6 Fahrenheit
Rectal37.5 Celsius which is equal to 99.5 Fahrenheit
Tympanic (Ear)36.8 Celsius which is equal to 98.2 Fahrenheit
Axillary (Armpit)36.4 Celsius which is equal to 97.6 Fahrenheit
These values represent normal body temperature on different sites.

FAQs

What is the formula for converting Celsius to Fahrenheit?

The formula to convert Celsius (C) to Fahrenheit (F) is:Celsius (°C) to Fahrenheit (°F)

What is the formula for converting Fahrenheit to Celsius?

The formula to convert Fahrenheit (F) to Celsius (C) is:Fahrenheit (°F) to Celsius (centigrade) (°C)

Why do we need to convert temperatures between Celsius and Fahrenheit?

Different countries use different temperature scales. Converting between Celsius and Fahrenheit is necessary for interpreting weather forecasts, medical readings, cooking recipes, and scientific data across different regions.

Are there other temperature scales besides Celsius and Fahrenheit?

Yes, other temperature scales include Kelvin (K), which is used in scientific contexts, especially in thermodynamics, and Rankine (°R), which is used in some engineering fields.
