What Is the Temp of Boiling Water?

Quick Scoop

When people ask “what is the temp of boiling water?” , they’re usually talking about pure water boiling at normal atmospheric pressure (sea level). In that common everyday situation, the boiling water temperature is 100°C, which equals 212°F.

Under typical kitchen conditions at sea level, boiling water stays at 100°C (212°F) while it boils, even if you keep adding heat.

The Simple Answer (Short Version)

Boiling point of pure water at sea level: 100°C (212°F).

“Normal boiling point” means measured at standard atmospheric pressure (1 atm).

While water is actively boiling in an open pot, its temperature stays around that value, not higher.

Why 100°C Is Not Always the Boiling Point

In reality, the temperature of boiling water depends on pressure and a few other details.

1. Atmospheric pressure and altitude

As you go higher above sea level, air pressure drops and water boils at a lower temperature.

At sea level (0 m): about 100°C (212°F).

Around 2,000 m: roughly 93–94°C (about 200°F).

On Mount Everest (8,848 m): about 71°C (160°F).

So if you’re cooking in a mountain town and wondering why pasta takes longer, your boiling water temp is lower than 100°C.

2. Pressure cookers and higher boiling temps

Increase the pressure, and water boils hotter.

In a pressure cooker, steam is trapped, pressure rises, and water can boil well above 100°C.

This higher boiling temperature cooks food faster because everything is exposed to hotter water and steam.

3. Impurities like salt

Dissolving things such as salt slightly raises the boiling point, a phenomenon called boiling‑point elevation.

Saltwater boils at a temperature a bit higher than pure water.

In everyday cooking, the increase is usually only a degree or two, not dramatic.

Quick Techy Note: Standard vs “Normal” Boiling Point

Scientists have slightly different reference pressures, so you may see slightly different “official” numbers for boiling water.

Normal boiling point (1 atm = 101.325 kPa): about 100°C (99.97°C).

IUPAC “standard boiling point” (1 bar = 100 kPa): about 99.61°C (211.3°F).

For practical kitchen and daily life, people just say 100°C / 212°F.

Mini FAQ and Forum‑Style Bits

Q: My kettle shows 100°C, but online I see 99.61°C. Which is right?
Both are effectively talking about the same phenomenon, just with slightly different reference pressures; for everyday use, treat boiling water as 100°C (212°F).

Q: Can boiling water be hotter than 100°C in an open pot?
Not under normal sea‑level conditions; once boiling, the temperature plateaus around the boiling point unless you change the pressure or the composition of the water.

Q: Why does food take longer to cook in the mountains?
Because water boils at a lower temperature there, so your boiling water is cooler than 100°C.

Today’s Context and “Trending” Angle

Even in 2026, “what is the temp of boiling water” still pops up in latest news explainers about climate, cooking tech, and viral experiments that show water boiling at room temperature in a vacuum chamber. As pressure‑based gadgets (like smart pressure cookers) get more popular, people increasingly search beyond the simple 100°C figure to understand why boiling temperatures change.

TL;DR

Standard answer: Boiling water is 100°C (212°F) at sea level under normal atmospheric pressure.

Higher altitude: Boiling point is lower than 100°C.

Higher pressure (pressure cooker): Boiling point is higher than 100°C.

Salt and other solutes: Raise the boiling point slightly.
