How do I measure this sleeping bag in Togs?

Primrose

Have just bought a new 16 oz sleeping bag in a charity shop which will double up a great spare duvet but I can't find out what the equivalent Tog rating is for 16 oz. Can anybody help please?

Why do you want to know what Tog rating it is?

It will either keep you warm, be too hot or too cold.

A tog measures thermal resistance; an ounce is a unit of weight. You cannot convert between these dimensions.

tog is a metric unit used to describe the insulating properties of cloth. If the flow of heat through the cloth is 1 watt per square meter, then the insulating value in togs is 10 times the temperature difference, in Celsius degrees (or kelvins), between the two sides of the cloth. This makes the tog equal to exactly 0.1 m2K/W

The tog is a measure of thermal resistance, commonly used in the textile industry, and often seen quoted on, for example, duvets and carpet underlay. The word may come from toga, a roman garment from which the English slang togs (meaning clothes) is probably derived.
The basic unit of insulation coefficient is the RSI, (1 m² K / watt). 1 tog = 0.1 RSI. There is also a clo clothing unit equivalent to 0.155 RSI or 1.55 tog [1]

Wish I understood that.

But I think to work out the tog , you will have to know what the filling is.
