iPhone Activity app - change display to calories or kilojoules

I'm not sure if this is the official way of doing this, but after Googling in vain, I've managed to change mine by going to the Health app on iPhone, then Health Data (at the bottom) > All > Active Energy

At the bottom there is a 'Unit' selection where you can change to kcal or kJ.

I've changed mine to kcal and now everything across the board displays as calories, whether it is on my apple watch / activity app / health app.

Hope that helps

Exactly the same thing here. Noticed that the iPhone app changed units from calories to kilojoules in ios9 but stayed calories on the watch. No option to change either anywhere that I can find??

I Have the same problem and haven't been able to find a solution. My preference is for Calories.

Same here, any ideas of how to change?

Legend @Lo_Mo... this solved it for me!

using the health app setting described above has resolved my issue. 🙂

Brilliant, thanks for this. Been really annoying me.
