Sorry for being off-topic, but why with all the advanced technology today I have to manually copy ounces and pounds into Google to learn how much it is? Instead of adding dark themes and material design, it would be better to add a unit converter.
Also do you really need a power bank for a 2-day trip? In airplane mode a phone can live like 2 weeks.
Under normal usage, even in airplane mode, some phones last only 12-48 hours after just three to five years.

On iOS:
Highlight text, select convert, see conversion:

But the real solution is for Americans to stop using dumb units.
On Pixel and Samsung:
Long press home button for "circle to search", draw line across text, see conversion.
Holy crap, I never knew that was a thing. Thank you!
If you have a mac as well, you can do these conversions in Spotlight.
Taking photos and videos does kill the battery quite quickly if you take a lot through. So does depend on what you use your phone for during your trip.
1 oz =~ 28 grams is a really useful conversion to remember
(signed, an American living in Europe)
28.4 grams. The rounding adds up quickly, and there’s comments here about people trimming borders off of paper maps. That .4 matters. Also, 16oz to 1lb.
Also matters when your buying things for recreational purposes. Especially when only buying points.
the point of knowing the rough conversion is to be able to do head-math to get a close number. I use 30 a lot of the time, b/c most of the time a close estimate is all I need.
if you're cutting off the borders of your map, by all means, use a calculator
And important that Troy is used for metals (31.1) That counts when 1g of gold is nearly $120usd
Grams are ounces. Ounces are pounds. Milligrams are grams. Micrograms are milligrams. Picograms are micrograms.
Yeah for pounds it's not so bad, you just do x2 and you're in the ballpark though not 200% accurate.
Ounces are more annoying to convert.
iPhone has one that's built in fwiw
