# How many joules and kWh is in a gallon of gasoline?

Contents

Refinery efficiency is about 90 percent and the energy content of a gallon of gasoline is about 132,000 Btu. Put that together and you have about 13,000 Btu of energy cost per gallon of gasoline produced, which is equivalent in energy terms to 4 kilowatt hours.

## How much energy is in a gallon of gasoline in joules?

Easy gallons of gas to J conversion. A U.S. gallon of gasoline contains 114,000 BTUs of energy, or about 120 million joules.

## How many joules are in a gallon?

1 gallon is equal to 131760000 joule.

## How many joules are in a gas?

To put how small a joule is into perspective, a liter of gasoline has 31,536,000 joules of energy in it. A kilowatt-hour is equal to 3,600,000 joules. Therefore, a liter of gasoline has 8.76 kW/hr of energy in it, which is a much more manageable number.

## What is the meaning of 1 gallon?

1 : a United States unit of liquid capacity equal to four quarts or 231 cubic inches or 3.785 liters. 2 : a British unit of liquid and dry capacity equal to four quarts or 277.42 cubic inches or 4.544 liters. — called also imperial gallon.

## How much gasoline does it take to produce 1 kWh?

Natural Gas: It takes 0.01003 Mcf (1,000 cubic feet) to make 1 kWh. This includes power plant inefficiency. Oil (residential fuel): It takes 0.0016 barrels to make 1 kWh.

IMPORTANT TO KNOW:  Why the oil and gas industry is bad?

## How many joules is a Litre of diesel?

One litre of diesel fuel (auto) has an energy content of approximately 38 MJ – which approximates to 10 kWh (using a ballpark figure) but the efficiency of conversion into kinetic energy is only about 30% – that is better than petrol which is typically 25% depending on the design.

## How many joules are in a kg of gas?

The formula used to convert kg to Joule is 1 Kilogram = 8.98755178780936E+16 Joule.

## How is GGE calculated?

Energy content is measured in British thermal units (Btus) per gallon of fuel, and is often referred to as the lower heating value of the fuel. To calculate GGE and DGE, the energy content of one gallon of gasoline or diesel is divided by the energy content of the comparison fuel.
