Hi,

I'm not sure if this has been brought up before, but here in little old New Zealand, we don't use Calories - we use kiloJoules. I'm sure we're not the only country :)

It would be handy if you could either include kJ in your application or at least have a converter on the site - currently I have to open 2 sites at the same time so that I can convert one way or the other,

Cheers,

Debra.

Ditto for Australia. kJ please! Love the iPhone app btw.
January 12, 2010 4:32 PM
OK, we'll work on it. What other countries use kilojoules? If you're from a country that uses kilojoules, let us know!

Hello creator - this is a fabulous site and I love the iphone app too. I have already got 4 of my own friends signed up for an account and I'll be telling lots more :)

Just one other thing - my status said that I lost 0.5kg since last weigh in (when it was only 0.1kg) and that I've lost 8.7kg overall, but it's only been 2kg.... am I doing something wrong?? Please help!

BTW - Just googled, seems all the European countries and just about every country outside of the US use kJ rather than calories :)
January 22, 2011 4:45 AM
Yes, whole Europian Union uses kilojoules. I vote to get such option in application (web, iPhone, android)

Here in the UK, food packaging such as weight watchers in shops show calories ie "400 cals per meal". I've never really looked at KJ's

The whole world uses kilojoules except the UK and US. It's ridiculous that you don't give people the choice of Calories or kilojoules. I signed up, then found out you didn't use kilojoules and I haven't used the site since. I've used kilojoules for dieting for 35 years, I'm not going to change back to Calories now.

Yes please! I'm finding it hard to read kJ on food labels and then have to convert it to cals when I enter it into the db.
You've given us kg for weight, so kJ for food would be great.
Thanks for a great service, this would just make it better!

Australia uses Kilojoules on *all* packaging.. I was surprised I could choose metric, but not kilojoules.

The only complaint I have about this app is that it doesn't support kilojoules. I'm using it regardless but would really hope to see it added as an option in a future version.
June 22, 2011 1:27 PM
Yes, I vote for an option that lets you set everything to Kilojoules instead of calories. It has prevented me for committing to this application for some time (an application which is otherwise wonderful!!)

South Africa also uses KJ, although I've got so used to doing the divide by 4.2 thing now :)

Hi Mike,
Great site - thanks for creating it!
My biggest bug bear is having to convert Kj to Calories. In fact it causes great dramas. I only use the app on my phone and when I add something new that is only listed in Kj, I insert the Kj value so that I can convert it later. This causes a massive pain when changing it, as it often does not sync and I end up with LOTS of duplicate entries! In fact, this is what has prompted my first visit to this site on line as opposed to on my phone. I'm hoping that the Greenblend Latte I've just fixed is now fixed properly! Now if only the other old duplicates (showing the Kj value in the calorie field that I was unable to edit) will go away some time!
Thanks again - I think this app is the beginning of a successful weight loss story for me!

From Australia here, and it would be awesome to have a kilojoule option. Everything packaged here has to have the Kj consumption however packaging does not require a calorie count and only some American and UK products include it. While you can receive a good estimate by dividing the kj's by 4 I believe it's 4.something in which cases I would need a calculator to work it out... So in finality I love the site and would really find it even more useful if a Kj option of intake was included.
Thank you

Hi, from NZ here...just adding my plug for kilojoules, please could a conversion be added so that we can enter in our Kj foods. :)

Hi all,

I'm of an age where I straddled the introduction of Metrication here in the UK, and mainly as a result of my education consider the Metric system superior to the Imperial/English units. That said, we still haven't got rid of Miles, Pints, MPG and Calories - or to be pedantic - kiloCalories.

Anyway, back to the reason for posting.... not entirely unrelated to the OP's subject, when I was first setting up my profile I was a little surprised that even though I opted for Metric units, I still had to select my rate of weight loss in lbs.

Confusing !?!?!

Other than that small rant... great site!

Keep up the good work, guys,

Another plug for metric units please - that's kJ, metres, kg and litres (and their mm, gram and ml variants more appropriate to cooking). Why the US and UK persist in using antiquated imperial units is beyond me. You might also like to consider putting the date the right way round, ie dd/mm/yy, or perhaps use mmm to avoid ambiguity.

Otherwise - good site and good iPhone/Android apps.

Cheers

I'm from South Africa and we also use kj. I take the kj and divide by 4.184 and that gives you the calories. I know it's a pain but it work.wink

A simple way to convert kjs to cals is to divide the number of kjs by 4.2
Hope it helps

In the US, we really ought to switch to metric. Wanda Sykes has a routine about how doctors use the metric system, the patients don't know the system, so we end up being told the size of things in fruit. (e.g., you have a tumor the size of a cherry.)

Okay.

For the people who seem to think the UK are stuck in the dark ages.

We use BOTH.

We have BOTH on nearly every bit of food.

BUT the option there would be good for everyone.


(And I think it's pretty rude asking an American site to change the American date format when y'know, it's AMERICAN.)

Hi,

i think myfitnesspal is the best site(app) for diet and nutrition facts.
But is not ussable for me, because it uses only calories and not kilo joules.

Please add KJ to the app, many more people will use it.

One more thing to the creator: do you know, that state named Slovakia exists on the map ?
In application you do not have it.

Thank you

Another Aussie here....

It's weird that we can choose our weight in kilos but when it comes to cals /kjs we don't have the option...
September 20, 2011 11:01 PM
May I add my voice to the kilojoules option. It seems odd that in the settings one can choose other metric options (as opposed to imperial) but then are stuck working with calories. As many others have stated, most of our packaging here in Australia only supplies energy values in kJ. Having to use a conversion app to work out the calorie value is annoying. I'm sure it would not be that difficult to build in a conversion factor for those who choose metric over imperial.
