Switching between Fahrenheit and Celsius on your Klein Tools ET05 Digital Pocket Thermometer is easy. First, turn the thermometer on using the Power Button. The device defaults to Fahrenheit (°F). To change to Celsius (°C), simply press the °F/°C Select Button. The display will then show temperatures in Celsius. To revert to Fahrenheit, press the °F/°C Select Button once more. Remember, the thermometer always starts in Fahrenheit when powered on, so you can quickly switch to Celsius if needed.
