Hi,

Can someone advise how to convert from gallon to Kg.

Thanks.

Hi,

It really depends on what your measuring. If it's water, then that has a specific gravity of 1, so with the metric system 1 Kilogram of water is equal to 1 liter of water. That's nice the way they did that.

The conversion from 1 US Gallon to 1 Liter 3.785, so if your measuring water, then 1 gallon is equal to 3.785 Kg.

However other liquids have different specific gravity, and I remember from by flight training days that aviation gas was .7 or something like that, so you needed to work that out because of the weight of the aircraft when fueled. So if your measuring some other fluid that's not water, you need to scale the number by the specific gravity after converting.

That should do it.

Regards,

Grant

Where exactly does specific gravity help convert volume si units to imperial units?

because Kg is not a volume unit but a mass unit... (One would think that this sort of stuff is common knowledge in a tech industry... apparantly not...)

Hi,

Outside the US, Kg is more commonly known as Kilograms, and is a weight. I assumed thats what he was talking about.

Ah, so that's where the knowledgeable authoritarian style comes from.

It all fall's into place!

1 Gallon (US)= 3.785412 liter (l). 1 Gallon (UK)= 4.546092 liter (l). Which one of them are You looking for? Why do need to convert from volume to mass?

Convertion | 27 July, 2005

KG isn't weight, it is mass. In metric weight is measured in Newtons.

Hi,

Could be fueling an aircraft with flux? Need to make sure there is not too much mass, or weight or kilograms etc.......

1 us gallon = 231 in^3 (NIST) 1 inch = 2.54 cm 1 in^3 = 16.38cm^3 16.38 cm^3 X 231 = 3785.41 cm^3 1cm^3 = 1g (pure water) 3785.41 cm^3 = 3785.41g or 3.785.41Kg

Do I get credit for showing my work?

Mass and weight are different. Mass is the measure of how much matter an object has. Weight depends on mass and the value of gravity. The units of mass and weight are also different. Mass is measured in kilograms and weight is measured in newtons.

Hi,

Yeah, but hey 99% of the population say they weigh xx Kilograms, so why fight it?

Coz' in 10 years we'll all be out there fixing second hand overdue space shuttles and we do want to be weightless, but certainly not massless...

(do we think EC got his answers yet?)

Weight varies based on gravity / altitute. Mass always constant.

Convertion | 3 August, 2005

Is mass always constant at different temps?

Convertion | 4 August, 2005

yes mass always constant irrspective of place / temperature ( without evoprating moisture or change property ).

thanks ajay, I was curious if volume and mass were the same. Much easier to ask here then actually look it up myself!

1. if you measure weight with same weighing scale it will be same irrestpective of temp / place. 2. But weight will be relatively different based on loaction if you compare from your present location. 3. if you check weight at moon respect to your loaction it will be about 1/6th & it is due to gravity. but mass will be same.
