How Long Does It Take To Boil 2 Cups Of Water – Nafa News

Once I was heading for a food recipe and wondered about, how long does it take to boil 2 cups of water? And wanted to know much more about boiling of water. Initially, boiling of water means raising temperature of water from 15°C (59 °F) to 100°C(212 °F) and time elapsed is to be calculated.

How long does it take to boil 2 cups of water, was observed using three mediums of boiling of water i.e. stove, microwave and kettles. While, boiling in stove, it took around 5 minutes to raise temperature from 15°C (59 °F) to 100°C(212 °F). In case of microwave, two cups of water was boiled in around 2 minutes. And in Kettle or water heater, in 1.5 minutes 2 cups of water got boiled.

How long does it take to boil 2 cups of water

In this observation, temperature of water before boiling was assumed as 15°C (59 °F) and atmospheric pressure as 1 atm as usual. 

Now, let’s this observation in an elaborated manner…..

How Long Does It Take To Boil 2 Cups Of Water in Stove

There are different types of stoves available. 

Natural gas stove, boils 2 cups (0.5L) of water in 3.5 minutes. Then propane stove took 4 minutes to boil 0.5L or 2 cups of water. Lastly, the electric stovetop stove boils 2 cups of water in 5 minutes. 

If we take the average of boiling time in different stoves, which is around to 4-5 minutes.

How Long Does It Take To Boil 2 Cups Of Water in Microwave

In case of boiling water in microwave, it depends on the power capacity of your microwave. In 750- 800 kwh, boiling of 0.5L or 2 cups of water takes 1.5 to 2.5 minutes. At the same time, 1.5 kwh microwave will boil 2 cups of water in 0.5-0.75 minutes.

How Long Does It Take To Boil 2 Cups Of Water In Kettle or Water Heater

Kettle with 2500 watts will take 1 to 1.5 minutes to boil 2 cups of water and the one with 1500 watts, boils 2 cups or 0.5L water in around 2 minutes.

Factors On Which Boiling Of Water Depends

Now let’s discuss some of the factors which may affect the boiling time of water.

Water Quantity

As we have discussed earlier half litre or two cups of water takes around 2 minutes to boil but if we increase the quantity of water to 1 litre, then the time taken will be 4 minutes. Therefore, quantity of water is a big factor in a boiling time.

Heating Methods

However, water can be boiled by various methods such as stove, microwave or kettle. Especially if you boil water with microwave it takes much lesser time than the stove. Therefore, with various heating methods, boiling time can also vary.

Impure Particles In Water

When tap water is boiled, it contains a lot of soluble substances which pollutes it, which increases the boiling period of water.

Heating Pressure

Pressure of your kitchen and the atmosphere has a great effect on boiling water. If the air pressure is high then it will take very less time to boil the water and if the air pressure is very high then it may take you longer to boil the water, as in cold places it takes a long time for the water to heat up because the air pressure remains on the high side.


Of course, the size and thickness of the container greatly influences the boiling of water. If you use a thicker container to boil water, it will take more time to boil and the thinner one will consume less time. But don’t use extremely small and thin container to boil water.

Final Thoughts

Indeed, how long does it take to boil 2 cups of water? Boiling water with various medium takes different amount of time as we have discussed above, such as stove, microwave and water heater or kettle. And, the average time to boil 2 cups of water with these mediums consumes around 5 minutes. But, this boiling time may vary at different altitudes, if you consider 1500 feet, then the boiling time will be 10 minutes. 

Although, there are some factors which influences the boiling of 2 cups of water which should be kept in mind. Finally, boiling of water for drinking is a good practices and make sure to boil the water until pathogens are completely killed.
