How many units of energy are consumed if one uses 10 litres of petrol?

If you are feeling the effects of a spike in your energy bills, or you are considering alternative options from a gas-fuelled boiler, then one of the main things you will need to know as a homeowner is how much gas your boiler typically uses. A number of factors feed into how much is used, but a good way of telling is simply by looking at the kWh of your boiler and its efficiency rating. The best way to measure gas consumption is to use kilowatt-hours (kWh), the standard unit of measurement. A typical low-consuming household’s annual use is around 8,000kWh, 12,000kWh for moderate consumption, and 17,000kWh for heavy-consuming homes per year. That puts a typical household’s monthly gas usage at around 1,000 kWh (a kWh representing the energy required to run a 1,000-watt appliance for one hour, so 1 KW is 1,000 watts). However, your residential gas use typically includes gas boilers, cooking, and other purposes. This means that when you are trying to calculate the exact gas usage of your boiler, it is not always clear where that gas has been consumed. A 30-kilowatt boiler consumes 30 kilowatt-hours worth of gas. If your 30kW boiler runs for five hours a day, your daily consumption should be roughly 150 kWh. With a current average price of 32.42 pence per kWh in Great Britain that amounts to roughly £1.62. In winter the average home is heated for approximately 8.7 hours a day, resulting in an average daily expenditure of £2.82 at an annual cost of £1029.50 for a 30kW boiler. ...

Quick navigation: • • • Fuel consumption formula The formula for calculating fuel consumption used in this online fuel consumption calculator is: Fuel consumption = Fuel used / Distance travelled The result depends on the metrics used as input: miles per gallon if the input was in miles and gallons, and km per liter if the input was in kilometers and liters. Additionally, the fuel consumption calculator will output the fuel cost per mile or fuel cost per km, depending on the metric units selected, as well as miles per $ / km per $. These are very useful when estimating your fuel costs and can help you predict your expenses easier on a future trip. For example, if you notice that your usually spend $0.15 per mile (15 cents per mile), then if you know you will be travelling for 200 miles, you can calculate the cost of the trip by multiplying 200mi x $0.15 = $30 for a 200 mile trip. Similarly, for km. Different ways to calculate fuel economy Fuel efficiency, or fuel economy, can be a tricky concept. Understanding that is key for the correct interpretation and comparison of gas consumption estimates such as those produced by this calculator. For example, say you want to compare two types of cars: A and B. You put two researches, one American and one French, to the task, with the first using kilometers per liter as an efficiency metric, while the second using liters per km. You have each researcher record the efficiency of 2 cars of each type, or, alternatively, the consumption...
