How to convert 1/2 US gallons of sea water to tonnes
To convert a quantity of a substance or material expressed as a volume to mass we simply use the formula:
mass = density × volume
We want to calculate the mass in tonnes from a volume in US gallons. We have the density table at the bottom of this web page that shows us the densities values in kg/m³, so we will use the folowing formula (see why below):
mass = d × v × vcfmcf, where mcf is the conversion factor to convert from tonne to kilogram (table near the end of this page) and vcf is the conversion factor to convert from US gallon to cubic meters.
So, plugging these values in the formula above, we get:
mass = 1025.18 × 0.5 × 0.003785411000
mass = 1.940361000
mass = 0.00194036 tonnes (answer)
There are other ways to convert from volume to mass. This is one of them.
How to convert from volume to mass (incorrectly called weight)?
Well, by definition of density we just need to use the formula:
mass = density × volume
Example: How much does 2 cubic meters of gasoline weigh in kilograms if the gasoline density is 750 kg/m³?
Plugging the values in the formula, we get
mass = density × volume = 750 × 2 = 1500 Kg
Very simple isn't it? Yes, it is as simple as that. But this works fine when the density value we have (from a chart for example) is defined using the same unit of volume and mass that we will use in the formula. For example, mass in kg and volume in liters. If we have, for example, mass in pounds and volume in gallons, we should do something to correct our result.
To transform the mass from pounds to kilograms we should multiply the mass in pounds by 0.45359237. We will call 0.45359237 the mass conversion factor - mcf
Matematically we write:
mass in kilograms = mass in pounds × mcf or
mkg = mlb × mcf (1)
To transform the volume from gallons to cubic meters we should multiply the volume in cubic meters by 0.003785411784. We will call 0.003785411784 the volume conversion factor - vcf
Matematically we write:
volume in cubic meters = volume in gallons × vcf or
vm³ = vgal × vcf (2)
Now, dividing the equation (1) by the equation (2), we get
mkgvm³ = mlb × mcfvgal × vcf, or
mkgvm³ = mlbvgal × mcfvcf, but mkgvm³ is, by definition, the density (d) in kg/m³, so
d = mlbvgal × mcfvcf
Rearranging the formula above we get
mlb = d × vgal × vcfmcf
Finally, we can generalize this formula any units of mass and volume, since we know how to find the values for mcf and vcf (Check the factor tables below).
m = d × v × vcfmcf
That is exactly the formula that we use in this calculator. You can see how this formula works reading the example above or/and choosing another one at the bottom of this page.
