Conversions for QR

Yup..it comes up all the time..I was told to know Mile to Km or vice versa. or Know the Temp stuff really well( F to C or C to F and C to Kelvin). Can someone Post them up the formula for all of them?

PS. you need to know Kg to gram, foot to miles . Cant think of anything else for now.but if I rmr somthing I will post them up.

 

C=5(F-32)/9 then you should know the conversion to Kelvin
1mile=1.6km

 

bump. Is there anything else we need to memorize? formulas for surface area, sphere, etc?

 

I think one big one is feet to yards, otherwise they may just give you harder conversions. I think I had a temperature question, and they gave me the conversion on the test.
