Steps converte kilometers

good morning, I would like to know if your application is precise… the reason I did 9 km and 10,080 steps… I am 1.80 meters tall and weigh 87 kg… with the km calculations on the internet, 9 km is approximately 12,000 steps… so I I wonder why there are 2000 more steps??? Is it my GPS or are the steps indicative?? I await your news, best regards

Hi.
Application itself does not count steps - steps are counted by device steps counter sensor. All apps get data from that sensor. So this is matter of that sensor and the way device is placed while doing activity.
