    How do i convert USD/kg to USD/gallon? pl help

    Liquid A:
    Cost=1416 USD/gallon
    Specific Gravity=1.35

    Liquid B:
    Cost=120 USD/Kg
    Specific Gravity=1.67

    Thank you

    If it was water (specific gravity = 1), then 1 kg = 1 liter, and since 1 gallon ≈ 3,785 liter, that's
    120 USD/kg = 120 UDS/liter = 454 UDS/gallon

    I'll let you make the adjustment for the specific gravity of liquid B.

    I think you're off by a factor of 1000 on that conversion of gallons to liters. 1 gallon is about 4 liters.

    That was a European "decimal point" :wink:

    You may have to account for the temperature of the liquid depending on how precise your conversion needs to be.

    In his first post, the OP specified the required density values.
