Analgesia
Opioid Conversion Calculator
Convert one opioid regimen to another. The tool normalizes to total daily morphine milligram equivalents (MME), converts to the target opioid and route, and applies an optional cross-tolerance reduction — with every step of the math shown.
This tool is a conversion aid and does not replace clinical judgement. Equianalgesic ratios are approximate — always verify doses and consider patient-specific factors before prescribing.

Show calculation steps
- 1) Start: Morphine 30.0 mg PO/day
- 2) Convert to morphine equivalent: 30.0 mg × 1 → 30.0 mg MED/day
- 3) Convert to Hydromorphone (PO): 30.0 ÷ 4 → 7.5 mg/day
- 4) Cross-tolerance: 0%
- → Final conversion= 7.5 mg/day
