Custom density FAQs
Why is density required?
Because mass and volume are different measurements.
Where can I find density?
Use the product label, SDS, or technical sheet.
Can I convert without density?
No, not accurately.
Which density unit should I use?
Use kg/L.
What happens if density is wrong?
The gallon result is wrong by the same proportion.
