comment What metric to imperial conversions should I know for traveling to the US?
Quarts are used but you won't be too far wrong if you simply pretend quarts are liters. I do the opposite when traveling in liter territory.

comment Very confused about China visa (American) and the possible 24 and 72 hour exemption rules
@Calchas Look at the third line of my quote from TIMATIC. Multiple stops are permitted. You can't' have multiple stops without having a domestic flight. Therefore domestic flights are permitted, they're just subject to the 24 hour clock rather than the 72 hour clock.

@Calchas You won't even be admitted without suitable outbound tickets--the only way to violate it would be to not use the tickets you had. Note that you can make a domestic hop on it but doing so limits you to 24 hours, not 72 hours. The clock runs from arrival to the departure time of the leg of the flight that actually leaves the country--beware of flights with stops!

@GreenieMeanie A long string of Chinese visas--that's how they would know there were no overstays or other problems. As for why your entries don't qualify--there are two things. First, it's for air travel only. Second, if the arrival and departure locations differ you're limited to 24 hours--pretty hard to do by train.

comment Why aren't conventional mercury thermometers allowed onboard?
The problem is that the mercury-aluminum reaction is catalytic. The mercury just keeps eating, it's not consumed.

comment From booking to boarding: What is typically the shortest time to book a flight until boarding?
Second this. I've been on a plane 20 minutes after walking into the airport with no ticket or flight schedule. (Pre-9/11, family emergency, I knew there were a whole bunch of planes on the route I was flying so I just packed what I needed, headed for the airport and lucked out on the timing.)

comment Why have they announced to turn off phones while they are explicitly allowed?
Reading from a computer poses a safety risk--if things go bad that computer becomes a substantial projectile in the cabin. All objects of that size are required to be stowed for takeoff and landing. I think the issue with tablets is more a matter of not wanting to draw a line--my Kindle would be no more hazardous than a book.

comment Why do cities impose a tourist tax?
Also, tourists don't vote. It's a case of sticking it to the other guy.

comment Is an open-ended ticket more practical than a one-way ticket for touring China?
Beware that you might not get in without the onward ticket. I've never been asked for proof but we have a long track record of not overstaying from back before they had onward travel requirements.

comment Do electronics bought airside have to be fully charged?
Back in the pre-9/11 era I took a laptop through security with a very bad battery pack--it would die soon after the POST was completed. I warned the agent what would happen, he accepted seeing it start the boot process and then die. (I was only using it plugged in, the useless battery wasn't worth replacing.) It's possible they are more strict now, though.

comment Why does my phone's GPS not work in China?
@LieRyan The unit I was using certainly didn't have 3G/4G location. It was pure GPS. This was in the late 90s and it was an old unit besides. I could only get a fix on satellites high in the sky and that's not enough.

comment Why does my phone's GPS not work in China?
@unforgettableid I have no idea what it might have downloaded--probably nothing as I don't think it had any non-volatile memory. It worked in open areas or high up, even with acquisition it would then fail if you tried to walk down a street.
