CALORIE/JOULE CONVERSIONS

KILOCALORIES TO CALORIES

• How many calories are in .75 kilocalories?
• One calorie is equal to one thousand kilocalories, so...
• .75kcal x 1000 = 750 calories

KILOJOULES TO JOULES

• (1 kj =1000 j)
• SO.........
• 2.5 kj x 1000= 25,000 joules

JOULES TO CALORIES

• 1calorie= 4.184 joules
• so...
• 550 x 4.184 = .......calories

KILOJOULES TO CALORIES

• How many calories are there in 2.78 kilojoules?
• This is a TWO-STEP process.
• First, convert kilojoules to joules:
• 2.78 x 1000 = 2780 joules.
• Next, convert joules to calories: 2780 x 4.184=...........joules.
