About Mila's Temperature Converter

Recipes call for Fahrenheit while your oven dial is Celsius; a weather app shows °C while a US thermostat uses °F; lab work wants Kelvin and some engineering tables use Rankine. Mila's Temperature Converter is a standalone app from the developer of Mila's Tools (Apple Staff Pick, 4.8 from 1,200+ reviews) that keeps five temperature scales synchronized on one screen.

Five scales, one entry point

Celsius, Fahrenheit, Kelvin, Rankine, and Réaumur (°Re) update together as you type. Hide scales you do not need, star favorites, and reorder them so everyday units stay on top. Smart formatting or manual precision (0–10 decimal places) handles both quick kitchen math and tighter scientific values.

When each scale matters

  • Celsius and Fahrenheit — cooking, weather, travel, and household thermostats
  • Kelvin — SI science, chemistry, and astronomy where offsets must anchor at absolute zero
  • Rankine — engineering contexts tied to the Fahrenheit interval
  • Réaumur — historical European texts, some food-science references, and specialty recipes

Designed for daily and technical use

Comfortable and compact layouts, dark mode, swipe-to-copy, and a custom numeric keyboard on iOS make repeated conversions fast. The app runs on iPhone, iPad, and Mac without requiring an account.

Frequently asked questions

How many temperature scales are supported?
Five: Celsius, Fahrenheit, Kelvin, Rankine, and Réaumur.
Can I show only Celsius and Fahrenheit?
Yes. Hide any scale you do not use; favorites control what appears first.
Does Kelvin conversion account for absolute zero?
Yes. Kelvin and Rankine use proper offset relationships relative to the other scales you enter.
Is this the same as the temperature tool in Mila's Tools?
Same core converter, offered as a focused app for people who only need temperature.
