Water does not boil at STP. STP stands for standard temperature and pressure. You've got to either increase the temperature or decrease the pressure.
Most likely you want to know what the boiling point of water is at standard pressure. This is complicated somewhat by the fact that STP is not as simple as it used to be and is now defined by IUPAC as 100 kPa but by NIST as 1 ATM (101.325 kPa). Using NIST standard pressure, the boiling point of water is 373.15 K; using IUPAC's value, it's 372.78 K (approximately... I couldn't find exactly 100 kPa in my vapor pressure tables, so I had to interpolate a little; that last digit may be off slightly).
Somewhat less likely is that you want to know what pressure is required to make water boil at standard temperature. Again, two competing standards; IUPAC's is 273.15 K and NIST's is 293.15 K. IUPAC's value leads to a pressure of 4.579 Torr, which is 0.610 kPa; NIST's value yields a pressure of 17.535 Torr or 2.34 kPa.
All values are straight from vapor pressure tables in the CRC Handbook of Chemistry and Physics (60th Ed.) modulo a units conversion, except for the one for IUPAC standard pressure which I had to interpolate as noted above.

What is a boiling point on Fahrenheit scale?
Pure water at STP boils at 212 degrees Fahrenheit.
What are the boiling point and the freezing points of water in Fahrenheit and Celsius?
At STP ie (1 Atm or 101.325 kPa, 760mm Hg) The boiling point of pure water is 212 °F or 100 °C The freezing point of pure water is 32 °F or 0 °C
What is water's boiling point in low atmosphere pressure?
Water's boiling point is lower in low atmospheric pressure compared to normal atmospheric pressure. At a pressure of 0.1 bar, water's boiling point is around 50°C (122°F) instead of the usual 100°C (212°F) at standard atmospheric pressure.
What is the effect of salt in boiling water?
There are two classes of constants for solvents. They are ; - Ebullioscopic Constants; raising of boiling point when a solute is a present. Cryoscopic Constants ; depression of freezing point when a solute is present. Pure Water boils at 100oC at STP. On addition of a say sodium chloride (common table salt) the boiling point will be raised, to about ??? 101oC Conversely, pure water freezes at 0oC at STP . On addition of salt again , the freezing point will be lowered. NB Used on roads to prevent surface water from freezing. NNB Aluminium oxide is dissolved in cryolite, so that it is melts/liquid at a lower temperature, in the electrolysis on bauxite to make aluminium.
What does the boiling of salt water compare to the boiling point of fresh water?
The boiling point of salt water is higher than that of fresh water because the presence of salt increases the boiling point of a solution. Salt water requires more energy to come to a boil compared to fresh water at the same atmospheric pressure.
What Is The value of the boiling point of water on the Kelvin scale is the value of the boiling point of water on the Celsius scale?
Pure water at STP boils at 100 degrees Celsius, which is 373.15 Kelvin.
What is a boiling point on Fahrenheit scale?
Pure water at STP boils at 212 degrees Fahrenheit.
What is oygen boiling point?
Oxygen is boiling at 90.20 K (-182.95 °C) when at STP
Why is octane a liquid at SATP?
Petroleum is a MIXTURE of organic compounds, all of which are above their melting point at STP and some of which are near their boiling point at STP. This means that at STP petroleum is a volatile liquid.
How are water and the metric system related?
the unit of mass is the mass of one cubic centimeters of water at STP. - gram the unit of temperature (degrees Kelvin or Kelvins) is related to the difference between the freezing point ofd pure water and the boiling point at STP. - Celsius, reduced to absolute zero for Kelvin.
