Weight percentiles are best interpreted with reference to height (see calculator for Infant weight for length percentiles.)
- Percentile conversion from Z-Score is done by table look-up in the standard Normal Table. Percentiles are provided for Z Scores between -3.09 and 3.09. Values beyond these extremes return percentiles of 0.1 and 99.9 respectively.
