plasma widget reports wrong temperature

[maestrobwh1]

I get it in degrees F and it is wrong. If I do

cat /proc/acpi/thermal_zone/TZ00/temperature
temperature:       46 C

e

but the temperature widget reports it as 57.5 F

The conversion that I know to be true and correct as a chemistry teacher is 1.8C = F - 32, or as an estimate, the Fahrenheit is double the Celsius and add 30.

46*2 + 30 would give 122F as ballpark.

It should be reporting, if it picks Fahrenheit (and I don't know how to configure it to use Celsius, as there seems to be no option) 46C as 114.8F

Is this a bug?

Re: plasma widget reports wrong temperature

Here the "System Monitor - Temperature" is a simple widget. It reads the temperature from the lm-sensors /1/. It does not convert - it just reads the numerical value.

The sensors command is telling:

:~$ sensors
asb100-i2c-1-2d
Adapter: SMBus nForce2 adapter at 5500
VCore 1: +1.70 V (min = +1.31 V, max = +1.97 V)
+3.3V: +3.28 V (min = +2.96 V, max = +3.63 V)
+5V: +4.95 V (min = +4.49 V, max = +5.51 V)
+12V: +11.73 V (min = +9.55 V, max = +14.41 V)
-12V (reserved): -12.26 V (min = -0.00 V, max = -0.00 V)
-5V (reserved): -5.14 V (min = -0.00 V, max = -0.00 V)
CPU Fan: 4245 RPM (min = 18243 RPM, div = 2)
Chassis Fan: 3229 RPM (min = 3183 RPM, div = 2)
Power Fan: 3947 RPM (min = 6958 RPM, div = 2)
M/B Temp: +48.0°C (high = +80.0°C, hyst = +75.0°C)
CPU Temp (Intel): +24.5°C (high = +80.0°C, hyst = +75.0°C)
Power Temp: +126.0°C (high = +80.0°C, hyst = +75.0°C)
CPU Temp (AMD): +25.0°C (high = +80.0°C, hyst = +75.0°C)
cpu0_vid: +1.650 V

If i change: System Settings > Regiaonal&Language > Other > Measurement system: Imperial. The plasma-widget will show Fahrenheit (F) symbol instead of the Celsius (C). No conversion.

/1/ package lm-sensors.

utilities to read temperature/voltage/fan sensors

Lm-sensors is a hardware health monitoring package for Linux. It allows you
to access information from temperature, voltage, and fan speed sensors. It
works with most newer systems.

This package contains programs to help you set up and read data from
lm-sensors.
