**The term “2-ton air conditioner” refers to the cooling capacity of the air conditioning unit, and it is a measure of the unit’s ability to cool a space. **

The cooling capacity of air conditioners is expressed in British Thermal Units (BTUs) per hour. A 2-ton air conditioner can remove 24,000 BTUs of heat per hour from a space.

In practical terms, this means that the air conditioner is designed for an area or room size of 1,000 up to 1,500 square feet, and the “2-ton” designation helps to estimate its cooling capacity.

The higher the tonnage, the greater the cooling capacity.

**Estimating electricity consumption: A guide for 2-Ton air conditioners with conversion table**

The electricity consumption of a 2-ton air conditioner can vary based on factors such as the specific characteristics of the air conditioner, the efficiency of the unit, the size and insulation of the home, regional climate conditions, and individual preferences regarding temperature settings, and of course, how often it operates.

First, here are some key numbers to bear in mind if you intend to consistently perform the estimative calculations on your own:

Let’s calculate now:

**2 Ton = 2 x 12,000 BTU/h = 24,000 BTU/h**

or

**2 Ton = 2 x 3,517 W = 7,034 W**

or

**2 Ton = 2 x 3.517 kW = 7.034 kW**

So, a 2-ton air conditioner has a cooling capacity of approximately 24,000 BTU/h, and a power consumption of 7 034 W, or 7.034 kW.

Use the table below for an easy and convenient conversion between BTU/h, Tons, and kW:

BTU/h |
Ton |
kW |

6,000 | 0.5 | 1.76 |

12,000 | 1 | 3.52 |

18,000 | 1.5 | 5.28 |

24,000 | 2 | 7.03 |

30,000 | 2.5 | 8.79 |

36,000 | 3 | 10.6 |

42,000 | 3.5 | 12.3 |

48,000 | 4 | 14.1 |

54,000 | 4.5 | 15.8 |

60,000 | 5 | 17.6 |

To determine the exact energy consumption of a specific 2-ton air conditioner, you can refer to the unit’s specifications.

The AC’s Energy Efficiency Ratio (EER) and Cooling Seasonal Performance Factor (CSPF) are also metrics used to assess the energy efficiency of air conditioning systems.

Additionally, checking the manufacturer’s information or the unit’s energy label can provide more accurate details on energy consumption.

**Estimating annual, monthly and daily electricity consumption of a 2-ton air conditioner: A calculation example**

This serves as an illustrative example.

Let’s assume that your air conditioner operates, on average, for 8 hours per day:

- 2-ton air conditioner = 24,000 BTU
- Daily usage = 8 hours
- 1 Watt = 3.412 BTU/h
- 1 Kilowatt = 3412 BTU/h
- 1000 W = 3,412 BTU/h – conversion factor (these are BTU per hour (power) and not BTU (energy)).

Calculate the electricity consumption using the following formula:

or

**Power Consumption (Watts) = 24,000 / 3.412 = 7034 Watts or 7.034 kWh**

Let’s proceed with estimating the yearly, monthly, and daily electricity consumption:

**Calculate Daily Consumption:**

*Daily Consumption (kWh) = 7.034 kWh x 8 hours ≈ 56.272 kWh*

**Calculate Monthly Consumption:**

*Monthly Consumption (kWh) = 56.272 kWh x 30 days ≈ 1,688.16 kWh*

**Calculate Annual Consumption**

*Annual Consumption (kWh) = 1,688.16 kWh x 12 ≈ 20,257.92 kWh*

Therefore, in this specific example, a 2-ton air conditioner with a cooling capacity of 24,000 BTU and daily usage of 8 hours would consume approximately *56* kWh of electricity per day, or *1,688* kWh per month, or *20,258* kWh per year.

NOTE: The above illustration is merely a hypothetical scenario. The real energy usage of your particular air conditioner is contingent upon various factors, including the AC’s capacity, EER, SEER, type, room dimensions, age of the unit, and also, the daily operational hours (not everyday you will use it for the same amount of time, you might not even use it everyday for 30 days!), the temperature settings, the season, among other considerations.

**Accurate electricity measurement: Using watt meters to gauge air conditioner power consumption**

There is a way for you to accurately determine the electricity consumption of your air conditioner (or any other appliance).

To precisely gauge the wattage consumption of your particular air conditioner you can use a watt meter for measuring its power usage.

Watt meters, such as the Poniie PN2000 Plug-in kilowatt electricity usage monitor are plugged into the power socket and then your air conditioner is plugged into the watt meter.

Subsequently, this meter will provide a digital readout, indicating the quantity of kilowatts consumed by your air conditioning unit per hour.

NOTE: Please do note that when selecting an air conditioner for a specific space, factors such as room size, ceiling height, insulation, climate, number of occupants, and other environmental considerations should be taken into account to ensure efficient and effective cooling.
