How to Convert Clo to Square Metre Hour Degree Celsius per Kilocalorie
- 1 clo = 0.180265 m²·h·°C/kcal
- 1 m²·h·°C/kcal = 5.547388567 clo
- Example: convert 15 clo to m²·h·°C/kcal: 15 clo = 15 × 0.180265 m²·h·°C/kcal = 2.703975 m²·h·°C/kcal
Reference conditions. m²·h·°C/kcal: International Table kilocalorie (4186.8 J).
Formula
m²·h·°C/kcal = clo × 0.180265
or m²·h·°C/kcal = clo ÷ 5.547388566832
Derivation from SI units:
- 1 clo = 0.155 m²·K/W (ISO 7730, ASHRAE 55).
- 1 m²·h·°C/kcal_IT = 3600 s ÷ 4186.8 J × m²·K ≈ 0.85985 m²·K/W.
- 1 clo = 0.155 m²·K/W ÷ 0.859845227859 m²·K/W per m²·h·°C/kcal = 0.180265 m²·h·°C/kcal
Both units are defined exactly, so the factor is exact. Clo definition: clo; Square Metre Hour Degree Celsius per Kilocalorie definition: square metre hour degree Celsius per kilocalorie.
Worked examples
- A reading of 0.7 clo converts to 0.1261855 m²·h·°C/kcal.
0.7 clo × 0.180265 = 0.1261855 m²·h·°C/kcal - A value of 1.5 clo is 0.2703975 m²·h·°C/kcal.
1.5 clo × 0.180265 = 0.2703975 m²·h·°C/kcal
