How to change your Smart Ear from °C to °F

The Kinsa Smart Ear thermometer can show temperatures in both Fahrenheit (°F) for Americans 🇺🇸and Celsius (°C) for the rest of the world. 🌎

Note: Kinsa thermometers and the Kinsa app handle their temperature scales separately. If you change the scale in your Kinsa app, it won't change the scale on your Kinsa thermometer's built-in display.

The steps for changing the temperature scale on your Kinsa Smart Ear thermometer are different depending on whether or not it has a side button:

If your Kinsa does have a side button:

  1. Turn over your Smart Ear and slide the battery cover down to open the compartment.
  2. Remove the batteries.
  3. Behind the batteries, you'll see a black and silver switch.  
    • For Fahrenheit (°F) pull the switch down away from the Smart Ear's ear sensor.
    • For Celsius (°C) push the switch up towards the Smart Ear's ear sensor.
  4. Replace the batteries and battery cover.
  5. Turn on your Smart Ear and you'll see the new temperature scale on the display.

If your Kinsa does not have a side button:

  1. If you have already connected your Kinsa thermometer with the Kinsa app, skip to Step 2.

    Click the button to turn on your Kinsa thermometer and wait for APP to appear, then quickly double-click the same button. The APP message will disappear and change to three blinking lines. - - -
     
  2. Turn on your Kinsa thermometer and wait for the three blinking lines to appear. - - -
  3. Quickly double-click the round button to change the temperature scale, eg. from °C to °F. 

    If the temperature scale doesn't change immediately, you may not be double-clicking the button quickly enough. You'll need to double-click the button with the same speed as double-clicking a mouse.
