Temperature conversion: Celsius, Fahrenheit & Kelvin

Starting with version 0.4.0, CalNote supports temperature conversions between Celsius, Fahrenheit, and Kelvin — right alongside the currency features you already know.

How it works

Append a temperature unit after any number. CalNote recognizes three formats for each scale:

• Celsius — °C or celsius
• Fahrenheit — °F or fahrenheit
• Kelvin — K or kelvin

100°C                      100°C
212 fahrenheit              212°F
273.15 K                    273.15 K

Converting between scales

Use the to keyword — the same one you use for currencies:

100°C to °F                 212°F
32°F to celsius             0°C
0 kelvin to °C              −273.15°C
−40°C to °F                 −40°F

That last one isn’t a bug — minus 40 is the one point where Celsius and Fahrenheit meet.

Variables work too

Store a temperature in a variable and convert it later:

body = 36.6°C
body to °F                  97.88°F
body to K                   309.75 K

boiling = 100°C
boiling to °F               212°F

Mixing temperature units

Just like with currencies, you can do arithmetic with mixed temperature units. The rightmost unit determines the result:

20°C + 10°F                 78°F
100°C − 32°F                180°F

CalNote converts the left value to match the right value’s unit before performing the operation.

Autocomplete has you covered

Press Ctrl+Space to see temperature unit suggestions alongside variables and currencies. Temperature units are marked with a ° icon in the dropdown so you can tell them apart from currency codes at a glance.

Quick reference

// Freezing & boiling points of water
0°C to °F                   32°F
100°C to K                  373.15 K

// Room temperature
72°F to celsius             22.22°C

// Absolute zero
0 K to °C                   −273.15°C
0 kelvin to °F              −459.67°F
