I do it the same as everything else - without converting in my head.
If you think of a number in English and then try to switch it over (Just like if you think of a word and then try to switch it over) it won`t work well.

I do have to pause for a second when hitting things over 億... But I think that`s more because the number itself is so big and I rarely use it in normal life.

It`s kind of strange because 100万 and a million are the same thing... But they exist as separate entities in my mind.
