'pressure-measuring' originates from the combination of 'pressure' and 'measuring', where 'pressure' refers to the force exerted by a fluid or gas, and 'measuring' refers to the act of determining the size, amount, or degree of something.

'Pressure' and 'measuring' have been used in English since the late Middle Ages, with 'pressure' deriving from the Latin 'pressura' and 'measuring' from the Old French 'mesurer'.

Initially, 'pressure' referred to the act of pressing, but over time it evolved to mean the force exerted by a fluid or gas. 'Measuring' has consistently meant determining the size or amount of something.
