Personalized Temperature Ranges

This tool allows you to determine whether your oral temperature is within the usual range for someone like you, based on your entered height, weight, sex, and time of day (between 7am and 6pm).

A black dot indicates where your temperature lies within the usual range for someone like you. The central line (50%) is your average by time of day. As the lines get further from the middle your temperature is moving further from your average. A dot placed outside the top line (99th percentile) or bottom line (1st percentile) would be an unusual temperature for someone like you.
