If gas is measured in cubic meters but the energy tariff is given in kWh, how can i determine the actual cost of energy consumption?
To determine the actual cost of energy consumption when gas is measured in cubic meters (m³) and the energy tariff is given in kilowatt-hours (kWh), you need to follow these steps:

1. Convert cubic meters of gas to kilowatt-hours:
To do this, you need to know the calorific value of the gas and the volume correction factor. The calorific value represents the amount of energy contained in the gas, usually expressed in megajoules per cubic meter (MJ/m³). The volume correction factor accounts for changes in gas volume due to temperature and pressure variations. You can find these values on your gas bill or from your gas supplier.

Here's the formula to convert cubic meters to kilowatt-hours:
```
kWh = (Cubic meters × Calorific value × Volume correction factor) / 3.6
```

The division by 3.6 is because 1 kWh equals 3.6 megajoules (MJ).

2. Calculate the cost of energy consumption:
Now that you have the energy consumption in kWh, you can calculate the cost by multiplying the consumption by the energy tariff.
```
Cost = Energy consumption (kWh) × Energy tariff (cost per kWh)
```
By following these steps, you can determine the actual cost of your gas energy consumption based on the given energy tariff in kWh.
