How do I convert Kjs to Calories?

Postby Dee » Sat Feb 24, 2007 10:42 pm

Okay, I posted this last night but it vanished, so I'm re-posting.

LOL - maybe that was divine intervention telling me to stop relying on you folks and start doing my own research, but hey this is easier!

I'm kinda calorie counting at the moment - just sort of rough figures so that I can keep an eye on how much I'm eating at each meal and for each snack, but I am having trouble with kjs v cals.

Does anybody know how many kjs are in a calorie?

Hi Dee

Hope this helps (and is easy to follow):

Converting from KJS (kilojoules) to Calories:

Multiply the number of kjs by 0.239

1 kjs = 0.239 Calories
320 kjs =76.48

Converting from Calories to KJS:

Multiply the number of Calories by 4.184

1 Calorie = 4.184 kjs
75 Calories = 313.8 kjs

If you are counting calories a good way to track it is in a diary like something such as calorieking.com.au just thought I would mention it because I use the website to count calories. It has most australian brand foods in there and deducts calories burned in your workout from your food intake.. i dont think I could count calories without it.

Good luck!

Dee, I use calorieking and find it absolutely invaluable. It is all there and you can either count cals or kjs. It also has a great diary to record everything so you can see where you are going right or wrong.

1 calorie is 4.18 kjs so when im on the run i just divide or multiple by 4

so if something is 800 kjs i divide it by 4 which is 200 calories, and if something is 150 calories i multiply it by 4 which makes it 600 kjs, its not quite exact but it works well if you dont have a calculator handy :P

I use google. You just need to remember what we commonly refer to as calories are actually kilocalories

Eg type into google search box: 'convert 400 kilocalories to kilojoules'

It also works for other measurements eg 'convert 160cm to feet'

If you want to be pedantic (which I'm always accused to being :oops:) 1 kilocalorie (what we wrongly call a calorie) is equal to 4.1868 kilojoules.

I use a program call Convert for all my convertions, hard to use if you are out and about though, but I love it.
You can convert anything to anything with it, so long as they are the same thing that is. eg: mass, energy, volume, area, etc. It's great. :)

It's a free program that my dad came across a while ago.
You can download it HERE, if anyone is interested that is.

Thanks guys - I'm not being really pedantic - but it's nice to have a formula to figure it all out.

I don't see anything wrong with being pedantic anyway Dee. Losing weight takes a lot of effort and focus so whatever helps you stick with it should be used.

I found during my weightloss phase being focused and knowing my calorie intake/expenditure helped me get to my goal. I used calorieking for my had food diary and exercise diary, spreadsheets to track my weightloss and a special program with my weight programs in it. In fact I still use most of that now on maintenance. This is not for everyone but it sure worked for me. :D
