Let us know when you own a scale that has 5 sides in a vacuum and just the measuring part exposed to air.

My ATV tires take 3 psi yet they don't collapse! Read up on atmospheric pressure.
Just wait until it comes out of rigor, of course.
It's 3PSI above atmospheric presure, dumbass.
You're the one that needs to do the reading. Pressure gauges do *not* measure absolute pressure. Google the difference between psig and psia.
Dude, I got one right here. But how do I use that to determine how much cold air I'm losing when I open my freezer?

Yeah - What Larry said! You tell em Larry!

Simple. Evacuate the air from the room. Place freezer on scale, take reading. Open freezer door, let air out. Take another reading. Subtract second from first.
What if you only have 40 minutes before your wife Bonnie comes home? (yet another movie reference - I'm on a roll)

Larry has no clue about this; obviously, neither do you. I'll give you the same advice I gave him: *you* read up on atmospheric pressure. Learn the difference between psig and psia.
Here, I'll help:
You'd need a gravity scale. lol
Actually you lose it all... if your upright freezer is a 10 cuft model within 2 seconds of opening the door ALL 10 cuft of cold air drops out like it was a lead balloon (minus however much cuft your food occupies).
With a chest freezer in still ambiant air practically zero cuft of air drops out, even if there is no door. Most stupidmarket food freezers/fridges are chest type and have no door... instead they have a fill line and many have add-on deflectors to block air agitation. Food stores are more and more moving away from upright freezer/fridge units.
So what?
Assume the freezer is half full (5 cu ft food, 5 cu ft air). Five cubic feet of food weighs about 250 pounds. Five cubic feet of air weighs about seven ounces.
Do you *really* believe that replacing seven ounces of zero-degree air with seven ounces of room temperature air is going to make *any* noticeable difference in the temperature of two hundred fifty pounds of food???
All the freezers and fridges in the isles (100-150 feet long x 4 rows), milk/dairy, and beer (about 80% of the store) are clearly the upright variety (doors and no doors). The only exceptions are the chests in front of the meat displays.

Good thing they have windows so you can see what is inside before you use a sawzall to gain entry.
I prefer freezers with doors wether it is an upright or chest. Makes gaining entry so much easier than the sealed types.
it's somewhere between an r.c.h. and a metric buttload.
your pal, blake
this must be the one home repair problem duct tape can't solve.

Word!
At sea level, moron?
You can't possibly be that stupid. It's an act, right?
Tire pressure gauges measure the difference between the pressure inside the tire and the pressure outside the tire.
