Can I use this calculator for any liquid substance?

Yes, you can select from common substances like water, milk, or cooking oil, or choose 'Other' and build a custom version for a specific concentration.

What if I need to convert from milliliters back to milligrams?

The calculator works in both directions; simply enter the volume in milliliters to receive the equivalent weight in milligrams.

How accurate are the conversion results?

The results are based on standard densities for the selected substances and provide accurate estimates for general use, but should not be relied upon for precise medical dosing.

Is this tool suitable for medication dosage calculations?

While the calculator includes common medication concentrations, it explicitly states it can never replace a professional doctor's assessment and should not be used for critical dosing decisions.
