convert 175f to c

Question

convert 325f to k
covnert 575 cal to J
canvert 23 Cal to J

Answer 1

F = (9/5)*C + 32
C = (F-32)*5/9
There are 4.184 J in 1 calorie.

Answer 2

I notice one of the calories is typed with a lower case c and the next one with an upper case C. Is that supposed to represent different units. In the OLD days, food chemists used the Big Calorie, usually represented by a capital C, to denote kcal while the small c was the regular calorie. If that is the intent here, then,
1000c = 1 kcal
