Body Heat Loss Calculator

Formula

The formula to calculate the Body Heat Loss is:

$Q = A \times \Delta T \times 5.67 \times 10^{-8}$

Where:

$Q$ is the Heat Loss in Watts
$A$ is the Surface Area in square meters
$\Delta T$ is the Temperature Difference in degrees Celsius

What is Body Heat Loss?

Body heat loss refers to the process by which the human body loses heat to its surroundings. This can occur through various mechanisms such as radiation, convection, conduction, and evaporation. The rate of heat loss is influenced by factors such as the surface area of the body, the temperature difference between the body and its environment, and the thermal properties of the surrounding medium. Understanding body heat loss is important in fields such as medicine, sports science, and environmental physiology, as it helps in designing appropriate clothing, medical treatments, and living conditions to maintain thermal comfort and prevent conditions like hypothermia or hyperthermia.

Example Calculation

Let's assume the following values:

Surface Area = 1.8 m²
Temperature Difference = 20 °C

Using the formula:

$Q = 1.8 \times 20 \times 5.67 \times 10^{-8} \approx 2.04 \times 10^{-6} W$

The Body Heat Loss is approximately 2.04 × 10^-6 W.
