Has anyone else run into a situation where your profile display preferences changes, on its own, from imperial to metric? I usually don’t notice until I am pedaling and my speed look a tad high 
I thought I had it figured out: SYSTM will sometimes forget which device I want to use for cadence and when I set it to my Sigma Duo it sometimes changes the units. But, it also happens without any changes to the devices.
Yep. Same! Irritating, but my Bolt used to do the same on an update now and again. I think it’s related to SYSTM updates as well.
There is only metric. All hail metric.
I learned to quickly multiply or divide by 1.60934 in my head. Nah…actually I just do 1.6.
I had this happen last week. It’s just the minions screwing with you. 
The only good use for metric is qualifying for a century… 
(Even if it is far more logical!) 
I don’t disagree that metric is useful in some instances. For hydration calculations, weight and water intake in metric is SO much easier.
But, being born and raised in the metrically-challenged USA I think in MPH and miles.
I usually go the opposite way: 100 k is ~62 mi
100 / 1.6 = ~63
63 x 1.6 = ~100
Close enough for government work, I guess.
We’re both right within a rounding error
Yes it happens to me also. Didn’t think it might be tied to Systm updates.
