When I weigh the first time each morning, the weight displayed is almost exatly 4 lbs heavier than subsequent weighs. The lighter subsequent weight readings are very consistent and closely match the reading I get on my older analog scale. Is there a calibration procedure for this scale or some other adjustment that I could perform which would result in more accurate weigh readings?

1 gallon of water weights a little over 8 lbs. google it for the exact amount

Let a be the weight of bag A, b the weight of bag B, and c the weight of bag C.
B weighs 4 times as much as bag A:===> b=4a
A weighs 3 times as much as bag C: ===> a =3 c
Combining the two relations: b=4a=4*(3c)=12 c
c= b/12
If you want the values, use the equation a= b-180
3c=12c-180. Solve for c to obtain c=180 /(12-3)=180/9=20
c=20 g, a=3*20 g=60 g, b=12*c=12*20=240 g
b/c= 240/20 =12

Let b be the weight of bag B, a the weight of bag A, and c the weight of bag C.
Bag B weighs four times as much as bag A -> b=4a
A weighs three times as much as bag C. --> a=3c
If bag A is 180 grams lighter than bag B--> a=b-180
Solve the system to find a=60 g, b=4*60=240 g, and c=60/3=20 g.
Thus b/c=240/20=12. Bag B is 12 times heavier than bag C or Bag C is 12 times lighter than bag B.

The weightof a sleeping bag can vary depending on the type you buy but there's no needfor it to weigh more than 5 lbs. You can buy ultra-light ones that weigh muchless. What are you using it for? If it's for hiking, you need a lighter onethan if it's for family use at home.

You say, that: "I have two Weight Watcher scales, model WW11D."

Can I have three guesses where you purchased them???
Do they come with any sort of warranty?

Their weight is inaccurate as compared to the official scales when you weigh yourself at the Weight Watchers meeting.

Are the people running the Weight Watchers meetings absolutely and totally unable to provide an answer regarding these scales?

Compare any 3 coins vs and other 3: If the weight is the same, weigh the 2 remaining coins. If one side is heavier remove the lighter 3, and compare 2 of the 3 from the heavier side: If they weigh the same, the one not weighed is the odd coin, if the weight is different, you have found your odd coin on the scale.

jim's: 1 foot 6 in and 5 lbs
kim's: 1 foot 5 in and 4 lbs
mim's: 1 foot 6 in and 6 lbs
tim's: 1 foot 7 in and 5 lbs

20 pounds is what it holds, what the bottle weighs depends on what it is made of. A steel bottle and an allumnium one will weigh completly different but still hold the same amount.

Hope this helps,plz let me know

Weighing 1

Weigh 1 2 3 on the left and 4 5 6 on the right

If the weights are even go to Weighing 2a
If the left side is lighter go to Weighing 2b
If the right side is lighter go to Weighing 2c


Weighing 2a

Weigh 7 on the left and 8 on the right

If the left side is lighter then weight 7 is the answer
If the right side is lighter then weight 8 is the answer


Weighing 2b

Weigh 1 on the left and 2 on the right

If the weights are even then weight 3 is the answer
If the left side is lighter then weight 1 is the answer
If the right side is lighter then weight 2 is the answer


Weighing 2c

Weigh 4 on the left and 5 on the right

If the weights are even then weight 6 is the answer
If the left side is lighter then weight 4 is the answer
If the right side is lighter then weight 5 is the answer
