Title: Currency and Unit Conversions
Post by: adamnsu on March 05, 2020, 12:45:03 PM
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 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??

This is in general wrong, no wonder you have problems finding the answer.

Specific gravity is what you need to convert between mass and volume.

Can you asisst by providing the right solution please?

No, that's not how the forum works. Please the forum rules (https://www.chemicalforums.com/index.php?topic=65859.0).

I told you: start by using the specific gravity to convert mass to volume.

Do you know how the dimensional analysis works? What are units of mass here? What are units of volume? What are units of specific gravity?
