You measure it at a particular temperature, or look up a convenient table.

Explanation:

I don't know how water vapour pressure is measured. I know that at #100# #""^@C#, the vapour pressure of water is #1# #atm.#

At temperatures below he normal boiling point, saturated vapour pressures are extensively tabulated. When you collect a gas by bubbling it thru water, you must always quote the saturated vapour pressure at the particular temperature.
