Thermie

A thermie (th) is a non-SI metric unit of heat energy, part of the metre-tonne-second system sometimes used by European engineers. The thermie is equal to the amount of energy required to raise the temperature of 1 t of water at $14.5 degC$ at standard atmospheric pressure by $1 degC$. The thermie is equivalent to $1,000 kcal$, $4.187 MJ$ or $3,968.3 BTU$.
