Everything about Tog Unit totally explained
The
tog is a measure of
thermal resistance, commonly used in the
textile industry, and often seen quoted on, for example,
duvets.
The
Shirley Institute in Britain developed the tog as an easy-to-follow alternative to the
SI unit of m
2K/W. Launched in the 1960s, the Shirley Togmeter is the standard apparatus for rating thermal resistance of textiles, commonly known as the Tog Test.
A tog is 0.1 m
2K/W. In other words, the thermal resistance in togs is equal to ten times the temperature difference (in
°C) between the two surfaces of a material, when the flow of heat is equal to one
watt per square metre.
According to British retailer
John Lewis, tog guidelines for duvets are as follows:
| Lightweight summer duvet: |
4.5 tog |
| Spring/Autumn weight duvet: |
9.0 - 10.5 tog |
| Winter weight duvet: |
12.0 - 13.5 tog |
Another unit of thermal resistance of textiles is the
clo, equal to 1.55 togs (1 tog = 0.645 clo).
