Gourt Home::Gourt :: Technical atmosphere
A technical atmosphere (symbol: at) is a non-SI unit of pressure equal to 1 kilogram-force per square centimeter, i.e. 98.066 5 kilopascals (kPa) or about 0.96784 standard atmospheres.
The symbol "at" clashes with that of the katal, "kat": a kilotechnical atmosphere would have the symbol "kat", indistinguishable from the symbol for the katal.
