Heating rate to hours

Use this converter to calculate total firing hours. It will convert heating rate (Celcious or Fahrenheit per hour) to hours
Add as many segments as you need, and the total duration (hours) will appear to the top bar ("Total Duration")
Holding time (soak) must be entered as minutes. For example 1hour and 30 minutes must be entered as 90 minutes.
"Full" power can not be calculated. In case you use "Full power" setting, you must enter the approximate rate (Celcious or Fahrenheit per hour) that your kiln is able to reach on full power.

Total duration:

Time to heating rate

Use this converter to convert a firing program which is expressed as hours to reach a temperature, to a program expressed as heating rate (Celcious or Fahrenheit per hour)
Add as many segments as you need, and the heating rate for each segment will appear to the right column ("Rate")
Time must be entered as hours and minutes. For example 1hour and 30 minutes.

* Heating Rate during the last 100°C of Firing
Cones do not measure temperature alone. They measure heatwork, the combined effect of time and temperature.
The role that heating rates have on the endpoint temperature is observed to be that the temperature required to cause a cone to bend will be higher for faster heating rates and lower for slower rates.
Heating rates that simulate fast, medium, or slow firings were tabulated.
