Select a fuel and units on both sides of the calculator and enter a quantity on the left side:

Examples:
1 gallon of gasoline = 24 gallons of hydrogen at 150 bar = 1.6 gallons of Ethanol.

They do not have a listing for E85.

I tested the calculator and it works with Mozilla and IE.

I hope someone finds this useful.

 

Has anyone used this calculator? Any problems? Any interesting results?

 

Cool calculator. There are a slew of books out now that tell us about "peak oil" and the end of the petrolium economy. Probably true. But this calculator shows that petrolium is hard to beat in energy storage ability. With current technology, alternate fuels will almost always need more storage space on the vehicle.

 

This calculator is an excellent tool to evaluate the relative efficiency of various fuels, especially in these days of gas crisis. Once, during my grad studies, I had a chance to work on a project to evaluate the feasibility of using soybean oil as a substitute for the gasoline and this research turned out to be quite positive!

 

Does anyone know if LPG is the same or close to the same as LNG or Liquified Natural Gas?

 

I would say no becuase lpg is liquid propane gas
my stove had two diffrent orcives one for LP one for NG the NG had a bigger hole the LP has a smaller one....

 

It has both propane and natural listed.

 

I thought propane was propane and LPG stood for Liquified Petroleum Gas, whatever that is.

I just Googled it and found:

Liquified petroleum gas (also called liquefied petroleum gas, liquid petroleum gas, LPG, LP gas, or autogas) is a mixture of hydrocarbon gases used as a fuel in heating appliances and vehicles, and increasingly replacing fluorocarbons as an aerosol propellant and a refrigerant to reduce damage to the ozone layer. Varieties of LPG bought and sold include mixes that are primarily propane, mixes that are primarily butanes, and mixes including both propane and butanes. Propylene and butylenes are usually also present in small concentration. A powerful odorant, ethanethiol, is added so that leaks can be detected easily. LPG is manufactured during the refining of crude oil, or extracted from oil or gas streams as they emerge from the ground.

At normal temperatures and pressures, LPG will evaporate. Because of this, LPG is supplied in pressurised steel bottles. In order to allow for thermal expansion of the contained liquid, these bottles should not be filled completely; typically, they are filled to between 80% and 85% of their capacity. The ratio between the volumes of the vaporised gas and the liquified gas varies depending on composition, pressure and temperature, but is typically around 250:1. The pressure at which LPG becomes liquid, called its vapor pressure, likewise varies depending on composition and temperature; for example, it is approximately 2.2 bar for pure butane at 20 °C, and approximately 22 bar for pure propane at 55 °C.

LPG was first produced in 1910 by Dr. Walter Snelling, and the first commercial products appeared in 1912. It currently provides about 3% of the energy consumed in the United States.

LPG is widely used as a "green" fuel for internal combustion engines as it decreases exhaust emissions. It has a RON that is between 90 and 110 and an energy content (HHV) that is between 25.5 megajoule/liter (for pure propane) and 28.7 megajoule/liter (for pure butane.) Toyota made a number of LPG engines in their 1970s M, R, and Y engine families.

 

okay my brain hurts now so I was semi correct? where we live (boonies) there is no natural gas everything is propane unless you get into the bigger city's

 

Maybe the "variable" composition is why they do not list a conversion for it. It would seem that variability would make it difficult to meter correctly for an automotive fuel. At least gas has standards unless it is gasohol. They should list a conversion for it also.

 

It looks like liquid propane is even worse than liquid natural gas. It takes 1.47 gallons of propane to equal a gallon of gas. It takes 1.35 gallons of liquid natural gas to equal a gallon of gasoline. Butane is a little better at 1.24 gallons.

 

what exactly are you working on? converting your old ford to dual fuel????

 

There were some user questions in General forums. Checking background info. I will stick with Gasoline.

 

oh okay figured after you got the front end swapp done you was needing a new project...
