About these units
The clo (clo) is a specialist or regional unit of thermal resistance, equal to 0.155 square meter kelvins per watt (rsi).
The tog (tog) is a specialist or regional unit of thermal resistance, equal to 0.1 square meter kelvins per watt (rsi).
Going the other way, 1 tog = 0.64516129 clo. Thermal insulance, better known as the R-value, measures how well a layer resists heat flow. It is the reciprocal of the U-value. US building products are labelled in ft²·°F·h/BTU, the rest of the world uses m²·K/W (RSI), duvets are sold by tog and clothing is rated in clo. Higher numbers insulate better.
