On a Temperature scale, the ice point is 25.6°I and the steam point is 155°I. If the temperature reads 66.6°I what is the equivalent in °C?
The Attempt at a Solution
25.6°I = 0°C
155°I = 100°C
1°I = 5/647 of the interval between boiling and freezing.
1C° = 647/500 I°
1I° = 500/647C°
66.6°I = 51.5°C
I arrive at this answer but i'm not convinced i've done this correctly. When changing from faranheit to celsius for example, I have to subtract the offset from zero...
So should my answer actually be 51.5 - 25.6 °C?
I'd really appreciate some help,
