245 Cal = 245 kcal = 245,000 calories
1 calorie = 4.184 J; therefore,
245,000 cal x (4.184 J/cal) = ? J.
?J x (1 kJ/1000) x (1 lb/14.6E3) = ?
1 calorie = 4.184 J; therefore,
245,000 cal x (4.184 J/cal) = ? J.
?J x (1 kJ/1000) x (1 lb/14.6E3) = ?

245Cal x 4182J=1.03x10(6)J
(14.6x10(3)kJ x 1000J)/1.03x10(6)J=14.2
Rounded to 3 sig figs
(14.6x10(3)kJ x 1000J)/1.03x10(6)J=14.2
