Would like a F to C and C to F helper option.
Just change your units
With my setup i dont even have a drop down for the temperature in any part of the settings(unless there’s some hidden preference somewhere).
My only reference to temp on HA is
mqtt:
sensor:
- name: "Wemos D1 Temperature"
state_topic: "home/wemosd1r1/temperature"
unit_of_measurement: "°F"
And if I remember correct my wemos is converting the temp for me.
I know of that option, but I was thinking more along the lines of having a default unit, but a helper in case you need the same sensor displayed in a different unit.
I’m new here though, and maybe that’s already an option? I just remember reading in the forums of people manually doing the conversion in YAML years back, and I figured I’d find a helper tool for that by now.
My last case use scenario involved calculating VPD with a sensor that was in F, and I needed C as to not make the formula more complicated. In the end though, I just opted for the VPD Chart HAC.
Apparently the idea is not too popular, so I understand either way. Thanks for the reply though!

I was thinking more along the lines of having the same sensor display C and F at the same time. A default unit, but the option to convert the default to C or F or K. If I change the unit, it’s just one or the other.
Just thought it would be neat. A helper, so you don’t have to manually do it in YAML, as I know some have.

Like this?
configuration.yaml
mqtt:
sensor:
- name: "Wemos D1 Temperature"
state_topic: "home/wemosd1r1/temperature"
unit_of_measurement: "°F"
sensor:
- platform: template
sensors:
wemos_d1_temperature_celsius:
friendly_name: "Wemos D1 Temperature (°C)"
unit_of_measurement: "°C"
value_template: >
{% if states('sensor.wemos_d1_temperature') not in ['unknown', 'unavailable'] %}
{{ ((states('sensor.wemos_d1_temperature') | float - 32) * 5 / 9) | round(2) }}
{% else %}
unavailable
{% endif %}
result

Exactly.
No votes for this Helper, so YAML it is 
Ill vote for it but the yaml still creates a helper
