Boiling Chart by Elevation

When calibrating a thermometer to measure very high temperatures it’s important to know what the exact boiling point is at your elevation. A quick calculation can be made by remembering three things: the boiling point at sea level is 212°F, your elevation and 500 feet. The boiling point of water drops by 1 degree as elevation increases by 500 feet. So, if your kitchen is situated about 1500 feet above sea level, then your water will boil at 209°F.

But to make it even easier, we've done the math and created this chart for quick reference.
