Temperature Reading draws a liquid-in-glass thermometer or a digital thermometer showing the temperature you type, in Celsius, Kelvin or Fahrenheit. On the liquid-in-glass thermometer students read the flat top of the colored column against marks every 1 °C, 1 K or 2 °F, estimating to 0.1, with an optional magnified view of the scale around the reading.
The digital thermometer is a handheld meter wired to a steel probe standing in a beaker, showing 0, 1 or 2 decimal places. Changing the unit converts the reading, so the same temperature can be shown in °C, K and °F for unit conversion practice, alongside questions on reading instruments in labs.
Copy the figure straight into a test, worksheet or slide, or download it as a PNG or SVG. Printing the page prints just the figure. Share link copies the page’s address with your settings in it, so anyone who opens it sees this exact figure, and presets save settings you use often in your browser. It’s free, with no sign-up.
Read at the flat top of the liquid column, with your eye level with it. Find the last mark below the top, then estimate one more digit: on a thermometer marked every 1 °C, read to 0.1 °C, like 23.4 °C.
There isn’t room for 1 °F marks over the thermometer’s range, so it is marked every 2 °F. Readings are still estimated to 0.1 °F.
The kelvin is an absolute unit, written K with no degree sign. The generator writes it that way on the scale and in the answer key.
No. Changing between °C, K and °F converts the reading you typed, so the thermometer shows the same temperature in the new unit.
