Clo Value Calculator

The Clo Value Calculator helps to estimate the thermal insulation provided by clothing, using the clo unit. One clo represents the insulation needed to maintain a person in comfort at 21°C (70°F) in a normally ventilated room.

Background Information

Clo is a measurement unit for the insulation provided by clothing, crucial for evaluating comfort in different environments. A higher clo value indicates more insulation. The formula takes into account the clo value, surface area, and temperature difference.

Example Calculation

If a jacket has a clo value of 0.8, a surface area of 1.8 m², and the ambient temperature is 5°C, the insulation provided would be:

\[ \text{Insulation} = 0.8 \times 0.155 \times 1.8 \times 5 = 1.116 \text{ W/m²} \]

This calculation is useful in determining whether the clothing is adequate for cold or warm environments.
