Frequently Asked Questions (FAQS)

What is the most accurate indoor/outdoor thermometer?

It is nearly impossible to get the very exact temperature readings due to constant changes in temperature. Therefore, the high-precision thermometers will only deliver a value closer to the actual condition; let’s say with the accuracy level of ± 10C. Our review covers the most dependable models the market holds currently.

Do mobile phones have temperature sensors?

As aforesaid, most smartphones have built-in thermometers. However, these sensors are not accurate since smartphones are not made for that. Therefore, if you need accurate readings, an indoor-outdoor thermometer is the best way to go.

What are the 3 units of temperature??

Temperature can be expressed in three units: Celsius, Fahrenheit, and Kelvin. However, Fahrenheit and Celsius are the most common scales in indoor/outdoor thermometers. Nevertheless, Kelvin remains the SI unit of temperature.

How do you convert from Fahrenheit to Celsius?

Fahrenheit is named after a German Physicist, Daniel Gabriel Fahrenheit and has the symbol F. This measurement unit is mostly used in the United States and is based on 32 for freezing point and 212 for the boiling point of water. Celsius is named after Anders Celsius and is the common unit of temperature in most parts of the world. Under this unit, the water freezes at 0 and boils at 100 degrees. To convert Fahrenheit to Celsius, subtract 32 and multiply the resulting unit by 5/9. To change Celsius to Fahrenheit, add 32 and multiply by 9/5.

Which is hotter Kelvin or Celsius?

The boiling point of water in Kelvin and Celsius scales is 100. Therefore, they respond at the same rate on temperature changes. Nevertheless, they are 5/9 the size of degrees Fahrenheit.

Which scale of measuring the temperature is the best?

Kelvin is the SI unit for temperature. Hence, it best defines what temperature is. Unfortunately, most temperatures use Celsius and Fahrenheit scales. However, you can rely on Celsius since the temperature increment intervals correspond to those of the Kelvin scale.


The fact remains that owning a reliable indoor-outdoor thermometer is important for every homeowner. However, getting that perfect model is easier said than done.

For this reason, we have pooled some of the market’s top options on our list of the top 11 indoor-outdoor thermometers. Just go through our review to find an excellent choice for your space!
