About the Temperature tool
Temperature scales have different zero points, so they are converted with an offset as well as a factor — this calculator handles the formulas for you.
Handy anchors: −40°C equals −40°F, 0°C freezes water, 37°C is normal body temperature and 100°C boils water at sea level.
