How much contraction

[JerD]

I tried to search but the key words(boiling, water, etc.) brought alot of unrelated posts to go through. What's the ball park figure for the difference in volume of just boiled water to cooled water? Or, how much does water contract as it cools?

4% is the number I usually see, from boiling to room temp-ish.
