Square meter kelvin per watt (RSI) quick reference
| Square meter kelvin per watt (RSI) | R-value (US) | Clo | Tog |
|---|---|---|---|
| 1 m²·K/W | ≈ 5.678263341 ft²·°F·h/BTU | ≈ 6.451612903 clo | = 10 tog |
| 10 m²·K/W | ≈ 56.78263341 ft²·°F·h/BTU | ≈ 64.51612903 clo | = 100 tog |
| 100 m²·K/W | ≈ 567.8263341 ft²·°F·h/BTU | ≈ 645.1612903 clo | = 1000 tog |
| 1000 m²·K/W | ≈ 5678.263341 ft²·°F·h/BTU | ≈ 6451.612903 clo | = 10000 tog |
