The '''pièze''' ({{IPA-fr|pjɛz|lang}}) is the unit of pressure in the [[Metre–tonne–second system of units|metre–tonne–second system of units]] (mts system), used, e.g., in the former [[Place:Soviet Union|Soviet Union]] 1933–1955. It is defined as one [[Sthène|sthène]] per [[Square metre|square metre]].  The symbol is '''pz'''.<ref>
