# The weight

I really need to start weighing my diapers in the morning. For the past month I have been luck to wear to bed every night. So in the morning before my shower I will drop my diaper off and sometimes it really makes a thud when it hits the floor. Also when I took the trash out the weight of a weeks worth of diapers was surprising. So I need to start a before and after weight.

I weight myself with my night nappy on in the morning, then weigh myself again when I take it off - so the difference is the nappy and contents weight. Our bathroom scales wouldn’t register the wet nappy on its own.

Does anyone know how much a litre of urine weighs? Is it close to 1Kg as per plain water?

Even baby diapers weigh a lot on Trash Day. "Ya gotta pay the piper if ya wanna be in diapers"!

All ya gotta do is weigh several diapers one at a time, add the total weight, divide that by number of dry diapers weighed and there's your average dry, or "tare" weight. Subtract that from your wet-diaper weight...and there ya go.

Agreed on that. But if (for example) the remaining weight is 1.5Kg, what volume of urine does that relate to?

Ok, so I’ve just checked with the internet and (as you may well expect) urine only weighs fractionally more than water. So, unless being pedantic, 1Kg = 1 Litre.

I do have a postal scale so I would get an actual weight. The only problem is doing it with out my wife seeing. She barely expects the fact I wear and use my diaper at night but if she seen me weighing a used diaper she would be "WTF!!"

On the other side of the discussion, determining the weight of a diaper after a full night can be seen as medical and also part of classification of what capacity diaper you should be wearing. A postal scale is great as the weight is well within its range! It will take several weeks to understand where your average will be. I then times that volume by a factor of '3' to assure a dry bed!

The good news is by understanding your average (tare) volume, you can select a diaper with greater volume to assure minimum leaks and as a result a happier wife as she is not faced with your leaking!

FYI: Assure you are not only meeting, but exceeding her needs and wants!
