There are numerous things to keep in mind when you are searching for a new refrigerator. But one of the most essential elements is how powerful it will be. There are a few ways of measuring this. These are by looking at the number of tons and kilowatts it offers. The good news is that there is a simple way to convert ton to Kw. Let’s take a closer look at how to do this.

What Is a Ton of Refrigeration?

A ton can seem like an odd term to use when discussing refrigeration. But it has fascinating historical roots. Before machines were invented to cool down buildings, people had to rely on blocks of ice. When machines started to come along, they needed a way of measuring how powerful the device was.

Because of this, the ton became the standard. This equates to 3.5kW. This is the amount of power it would take to freeze one short ton of pure ice (0 degrees Celsius) over a day. Today, this method of calculating refrigerating power is largely limited to North America.

Ton to kW: Formula

There is a simple that you can turn tons of refrigeration to kW. As we mentioned, 1 ton will equate to 3.516 kW. But how to convert ton to kW?

The answer is simple. If you want to convert tons to kW, you simply need to multiply the number of tons by 3.516. For example, two tons is 7.032 kW. On the other hand, 0.1 ton is .3516 kW.

What Is A kW?

How to Convert Ton to KW Easily
A kilowatt is simply a measure of how much power an electric appliance consumes—it’s 1,000 watts, to be exact.

While a ton is a measure of cooling power, a kW is a way of recording how much electricity the device is consuming. A kilo-watt will make up 1,000 watts. Once you know this number, you can compare the energy usage of appliances. It’s also important when going on a camping trip to ensure that you have enough generator power for your appliances. Our guide to the best 1,000-watt generators can help you find a compact model that is ideal for your next holiday.

kW to Ton: Formula

1Kw is worth 0.284 tons. There is an easy way to convert from kW to a ton of cooling power. To turn kW to a ton, you simply need to multiply the kW by 0.284, this will tell you the number of tons. For example, 10kW is 2.84 tons. While 5 kW is 1.42  tons.

Cooling kW to Electrical kW

The next thing to consider is the cooling capacity that the system can deliver. This is a way of measuring how much heat can be removed from a space. This is found by calculating the amount of cooling, in kW, divided by the amount of air that is passing through the system. You can learn more about the science behind cooling kW in this article Trusted Source Cooling Capacity The cooling capacity is defined as the amount of cooling (usually expressed in terms of kW or tons of cooling) delivered by the system divided by the amount of air passing through the system (in kg/s or cfm). .

To find the cooling power, it’s important to consider the Energy-Effiecency Ratio (EER). This tells you how much cooling power you will get based on the number of watts you are using. So, the higher the EER rating, the more efficiently your device will be running.

But how do you convert ERR to kW/ton? There are only two things that you need to know. First, you need to know the cooling capacity of the machine. This is often measured in Britsh Thermal Units (BTUs). Then, you need to know how much power is being supplied. This will need to be measured in watts. So, you will need to multiply the number of kW by 1,000. For example, 3.5kw is 3,500 watts.

Once you have this, you can divide the cooling capacity (BTU) by the power supplied (watts). This will tell you the EER. For example, a 12,000 BTU system powered by 1,200 watts will give an EER of 10. So, for every watt of power, you will experience 10 BTU worth of cooling power.

This calculation can tell you whether you will be getting a system that is affordable to run. The average EER for an air conditioner is 8.5. You can also consider the energy star rating when looking at appliances like fridges. The higher the star ranking, the more efficient it will be.

What Else To Consider When Choosing An Air Conditioner

An air conditioner that connects to your home network so you can control and monitor its output through an app on compatible tablet or mobile devices.

Knowing how to convert kW to ton will tell you a lot about the air conditioning system and how powerful it will be. But there are a few other metrics to take into account before you make your final decision.

First, it’s a good idea to consider the type of features that will come with the system. For example, does it come with a remote control? Is there a way to adjust the temperature? Sometimes, there will also be an economy mode, which will reduce the amount of power the machine needs to run.

The next thing you should consider is the size. This will often depend on the circumstances in which you plan to use it. For example, if you are going on a camping trip, you might want to consider getting a compact system that can be connected to a small generator. In this case, something like the BLACK+DECKER Portable Air Conditioner might be a good option. If you want to know which generator to pair it with, check out our guide to the best generators for air conditioners. If you prefer a more environmentally friendly option, consider our list of the best gasless generators.

On the other hand, you might want a system that will be powerful enough to cool a whole room. In this case, something like the hOmeLabs Window Air Conditioner might be a better choice. This type of air conditioner can comfortably slot into your window frame.

Final Thoughts

When looking at the air conditioner specifications, you might only be able to find the number of tons of cooling power it produces. Thankfully, it’s easy to turn tons to kW. As long as you can do this, you will have access to a wealth of information about the system you are thinking of purchasing. For example, you’ll be able to find how much power it will need and how much it will cost to run. Hopefully, this will allow you to find the ideal air conditioner to suit your needs.
