Need conversion help

  1. Jan 30, 2005 #1
    Hi newguy here :blushing:
    Heres the problem:

    If one fluid ounce treats 2-1/2 gallons, how many ounces (or mililiters) are to be added to a .45 liter tank?

    I want to add fuel stabilizer to my weed eater gas tank.

    IIRC,"ounce" (avoirdupoids) is a unit for MASS,while "gallon" is for VOLUME/CAPACITY...So u need the density...
    So it's not "OUNCES (or MILLILITERS)",but OUNCES...


    P.S.Roughly 1 gallon=~4.54l...In the UK,or 1 gallon=~3.78l in the US.

    I'll take mililiters also. Density? Don't know that. The bottle simply says 1 ounce treats 2-1/2 gallons (U.S.) The tank is .45 liters. Just assume the tank is full of gas. Maybe thats the density.

    0.45 litres is roughly 0.1 gallons (actually 0.099 british gallons or 0.119 US gallons - found this here, not sure which you're using). So if one fluid ounce treats 2.5 gallons and you want to treat 0.1 gallons you'll need 0.1/2.5 = 0.04 fluid ounces, which is little more than one millilitre:
    [tex] \frac{1\mbox{ fl-oz}}{2.5 \mbox{ gal}} = \frac{x \mbox{ fl-oz}}{0.1\mbox{ gal}} \implies x = \frac{1\mbox{ fl-oz}}{2.5 \mbox{ gal}}\times 0.1\mbox{ gal} = 0.04\mbox{ fl-oz}[/tex]
    Hope that helps.

    Thank you!

    Google is really very useful for these things. For example, you could type speed of light in furlongs per fortnight, and it will convert it for you.

    Just a tip :wink:
