Reporting clinical laboratory analyte concentrations where deciliters are commonly used.
Formulating small chemical volumes where 100 mL increments are practical.

Tips & Best Practices

Always confirm the type of cup measurement used in recipes or nutrition labels due to slight variation from the 'legal' cup.
Use this unit conversion for volume only; convert weight or mass separately if needed.
Be aware of possible rounding when applying results to scientific or clinical contexts.

Limitations

The US customary cup differs slightly from the 240 mL 'legal' cup used in some US nutrition labeling, causing minor discrepancies.
Rounding errors may appear, particularly in precise scientific applications.
This conversion applies only to volume measurements and does not account for ingredient density or weight.
