  • Currency and Unit Conversions

    Hi,

    I am having a bit of difficulty converting the following.

    Benzene USD/tonne 1450 to USD/GAL. Details provided 1MT= 264.172 Gallons and specific gravity 0.8787. So 1450*264.172 to change from tonne to gallons, but why does one have to multiply by the specific gravity?

    What if I wanted to change Benzene USD/tonne to GBP/tonne? if USD/GBP is 0.77.

    Please can someone show me the step by step of both calculations??

    Not correctly, as they are two different statements of the density. ( I thought you may have been given a figure for Imperial gallons but that doesn't check either.)

    1 t = 1000 kg. If SG = 0.8787, that is about 1138 L (will vary slightly with temperature and therefore density of the comparator water). The US gallon is approx. 3.7854 L/gallon so that would be 300.6 gallons, not 264.172. (It would be about 250.3 Imperial gallons)

    On the other hand, if you believe the gallons per tonne figure, it is 264.172 gallons and you don't need SG.

    They are two ways of doing the same conversion, but are in substantial disagreement. The SG for benzene is in relative agreement with other sources (0.876). If this is a proposed commercial contract, I recommend discussing the apparent issue before proceeding. Something is wrong.

    If you believe the gallons per ton figure (it is most likely wrong): Note that you need to divide by the gallon/tonne figure
    $1450/t x 1 t/264.172 US gallons = $5.489/US gallon

    If you believe SG (it is in the ball park for benzene)
    $1450/t x 1t/1000 kg x 0.8787 kg/L x 3.7854 L/US gallon = $4.823/US gallon

    Finally for US dollars per tonne, multiply by pounds/dollar (I assume your figure is 0.77/$1.00)

    NOTE: I can only use the slash (/) for a division symbol here, but the unit cancellation will be a lot more apparent if you write each fraction as a figure above and below a horizontal line.

    Sorry to ramble. I just noticed that 264.172 gallons x 3.785 411 784 L/gallons = 999.9998 L. Depending on how somebody rounded, 1000 L (or 1 kL or 1 m) not 1000 kg. I believe the figure 1MT = 264.172 Gallons is misrepresented, and 1 m = 264.172 gallons. 1 m is also 1 kL or 1000 L by definition.
    Then $1450/t x 0.8787 t/1 kL x 1 kL/264.172 gallons = $4.823/US gallon.

      JohnS You are a star mate! Thanks so much for that.

      I am giving a test this Monday at a company and looked up the conversion, and on their website someone put this us. You are quite right that something was wrong. Your brilliant method helped me figure it out.

      So according to the currency conversion $1450/tonne = $1450*0.77/tonne =1116.5/tonne (given that $1=0.77GBP)

      So if I get this right converting $1450/tonne into /Gallon = $4.823/US gallon*0.77 gbp=3.714 /US Gallon.

      I will another question which I will short properly and will be grateful if you wouldnt mind helping me out.

      Best wishes

        Yes but anyone who wants price in pounds sterling may want it it per Imperial gallon (what UK used to use) or per litre (which they presently use). The Imperial gallon is about 1.2 US gallons, but if you need a more exact number, I'd have to search for it.

        The US and UK have different size gallons, but liters and litres are exactly the same size.
