Convert between VAS, NRS, Wong-Baker Faces, and FLACC pain scales.
Approximate 1:1 mapping for reference only. Wong-Baker is shown on the 0-5 face scale (each face = 2 points on the 0-10 scale). FLACC is an observer-rated behavioural score for infants and non-verbal patients and is not a validated conversion of self-reported pain; score it directly at the bedside.
No. Pain Scale Converter is free, with no signup required, and nothing you enter leaves your browser.
Pain Scale Converter is built on published formulas and reference ranges from established health sources. We revisit it periodically as guidance evolves; the "Last reviewed" date above shows when that last happened. If something looks wrong, tell us with the feedback button in the bottom-right corner.
No. Pain Scale Converter gives you a general estimate based on the inputs you provide, not a diagnosis. Existing conditions, medications, and individual history all change what a number actually means for you. Treat this as a starting point for a conversation with a doctor or other qualified health professional, not a substitute for one.
