Relating to the measurement of temperature or using a thermometer.
The thermometric readings indicated a significant drop in temperature overnight.
Thermometric is formed from "thermo-" (from Greek "thermos", meaning heat) and "metric" (from Greek "metron", meaning measure). The word refers to the measurement of heat or temperature.
Think of 'thermo-' meaning heat and 'metric' meaning measure — so thermometric relates to measuring heat.
