How Long It Take for An Ice Cube to Melt

On a hot and warm day, if you want to get a glass of cold water, you must melt the ice cube first. But, how long does it take for an ice cube to melt?

You cannot wait for long as you’re very thirsty, and the warm environment is making you crazy, right? That’s why you want to melt the ice cube quickly to consume the cold water.

No matter how thirsty you are, you must wait for a minimum time until the ice cube melts.

Usually, a 1-inch ice cube takes 45 to 60 minutes to melt at 75-degree Fahrenheit room temperature. But make sure the initial temperature of the ice cube size is 1-inch, and the initial temperature is less than 20-degree Fahrenheit.

However, you can reduce the ice melting time by increasing the surrounding temperature up to 185-degree Fahrenheit. Just boil a 30-gram ice cube in the warm water by increasing the temperature to 185-degree Fahrenheit. The ice will take only 60-70 seconds to melt.

In the end, the ice melting time depends on the size, type, and temperature of the ice. Keep reading to learn in detail how long it takes for the ice to melt.

How Long It Take for An Ice Cube to Melt at Room Temperature?

Firstly, you must try to melt the ice cube at room temperature to get a glass of cold water. But, how long does it take for an ice cube to melt at room temperature?

Typically, the room temperature lies between 68 to 80-degree Fahrenheit. Indeed, the ice cubes at 80-degree F will melt faster than the ice at 68-degree Fahrenheit.

At 68 to 80-degree Fahrenheit room temperature, a 1-inch ice cube might take 45-60 minutes to melt. Furthermore, when the ice cube is 1 and 30 grams, it’ll take up to 120 minutes to melt at the 75-degree Fahrenheit room temperature. 

However, if you keep the ice cube at a hot temperature of 185-degree Fahrenheit, it won’t take more than 60-70 seconds to melt a 30-gram ice cube.

Some people try to melt the ice cube at a 32-degree temperature, taking excess time to melt the ice. Indeed, you cannot wait for such a long time to melt your ice cube, right?

How Long It Take for An Ice to Melt in Water?

It’s said that water works faster to melt the ice cube compared to the open air. This saying is actually the truth, and the reason behind this is the high density of water.

Undoubtedly, water is denser compared to the air; consequently, it offers more pressure to the ice cube than the airflow.

So, how long does it take for the ice to melt in water?

A 1-inch cube takes 5 to 10 minutes to melt in room temperature water. Even though the water is cold, the previous size ice cubes submerged into the water within only 15-20 minutes.

If you compared the timing with the ice melting in air, you’d admit water is a quicker way of melting ice.

How Long It Take for An Ice Cube to Melt in Cold Water?

It depends on the initial ice temperature, the water temperature, and ice volume; how long might it take for an ice cube to melt in the cold water.

Well, a 1-inch ice cube should melt into the cold water within 15 to 20 minutes. Regardless, you can get the ice cube melting faster by adding salt or sugar with the cold water.

Just put a spoon of salt or sugar into the ice-melting cold water and see what the result comes!

When an ice cube is submerged in hot water, how long does it take for it to melt?

The ice cube’s melting time is determined by how swiftly it absorbs heat, regardless of whether it is placed in hot or cold water. The faster the ice cube absorbs heat, the faster it melts.

So, how long does an ice cube take to melt in boiling water?

In 240 mL boiling water, a 1-inch ice cube dissolves in 40 to 45 seconds. A 30-gram ice cube, on the other hand, takes 60 to 70 minutes to dissolve in 240 ml water at 185°F.

In a nutshell, the higher the water temperature, the less time the ice cube will take to melt.

How Long It Take for An Ice Cube to Melt in Salt? 

When the ice cubes are kept in the salt water, they melt faster than the regular time. That’s because, the salt reduces the temperature of water more than the 

The application of salt reduces the freezing point of water quicker than freshwater.

Not only just salt, but sugar is also efficient in reducing the freezing point of the ice cube.

There’s no predetermined calculation of how long it can take for an ice cube to melt in the salt water. But, it’s proved that the salt water reduces the water temperature consequently, the ice melts in faster in the salt water.

What Are the Factors that Affects Ice Cube Melting?

How fast will the ice cube melt? It actually depends on the ice holding bucket, size and shape of ice cubes, insulation, and so on. Now, let’s discuss the factors of melting ice cubes in brief.


What is the type of ice cream holder? Usually, ice cubes are stored in plastic or metal ice buckets. The metal ice buckets conduct the heat quickly compared to the plastic ice buckets.

That’s because the plastic ice buckets have greater insulation compared to the metal ice buckets. Indeed, quick conduction of heat through the ice buckets melts the ice faster than the average time.

So, if your ice cubes are in the metal ice buckets, that’s a plus point for you. You can get your desired glass of cold water anytime at the lower time.


The ice cubes from the uncovered ice bucket melt faster than the ice cubes from the covered ice bucket. The heat can effectively be inserted into the open ice bucket as there’s no block or restriction.

Contrarily, the cover of the ice bucket blocks the heat from entering the bucket. 

Size and Shape of Ice Cube

Undoubtedly, a large ice cube will take much more time to melt compared to a small ice cube. So, if you store the ice cube in the small-shaped ice bucket, you can melt it faster when needed.

Contrarily, the large container ice cube takes longer to melt than the small bucket.

Types of Ice

The dark ice melts faster compared to the clear ice as it absorbs solar radiation more than the clear ice. That’s why dark ice has a lower lifespan compared to clear ice.

Room Temperature

Temperature and surrounding pressure also affect the time for melting the ice cube. The pressure at the hotter place is higher than the pressure of a normal place. Therefore, when you keep the ice cube in a warmer place, it melts faster.

Ice Temperature

The initial Ice temperature also affects its melting time no matter whether the environment is warm or cold. The ice with -10-degree Fahrenheit will take longer to melt than the ice with -20-degree F initial temperature.


A room temperature with good airflow is important to melt the ice cube at a lower time. A good amount of airflow circulates the heat into the ice cube when you keep it out of the freezer.

Fortunately, the heat circulation increases with good airflow more than regular; consequently, your ice melts faster.


Which Ice Cube Will Melt Fastest?

The rectangular ice cube melts faster compared to the crescent-shaped ice cubes. Furthermore, the ice cube at the hotter place melts faster than the ice cube from the cooler place.

How Do You Melt Ice?

Boiling the ice cube in hot water is a good way of melting it quickly. Furthermore, you can also quicken the ice melting process by adding warm water to the ice cube.

Salt, baking soda, and sugar are the other three effective ways of melting ice. If you don’t want to melt the ice with warm water, you can use these ingredients to lower the ice cube temperature.

How Long Does Ice Last Before Melting?

The ice cubes can last in the ice buckets for 4 to 18 hours before melting. It actually depends on the capacity of the cooler how long does ice lasts before melting.

When the cooling capacity is 20-Quart capacity, the ice cube lasts for 2 to 4 days; contrarily, the ice cube with 55-Quart capacity lasts for more than a week. Lastly, when you’re in a giant cooler, it’ll hold the ice cubes for more than 2 weeks for 14 days without melting.

How Long It Take for An Ice Cube to Melt in The Sun?

If you try to melt the ice cube under the sun, you’ll get quicker results for melting ice than the regular time. Under full exposure to the sun, a 1-inch ice cube takes only 4 minutes to melt completely.

The Sum Up!

Wondering About How Long Does It Take for An Ice Cube? Well, a 1-inch ice cube shouldn’t take more than 60 minutes at 75-degree room temperature.

Still, if the ice cube is taking more or less than this average time, that means there’s something to affect the ice melting time. Besides disclosing the average time for melting the ice cube, that’s why we’ve also disclosed several factors that can affect the ice melting time.
