This is actually quite workable if you do it the other way around. That is, fill the tub with an amount of water that will allow you to completely submerge yourself. Mark the water level on the tub with a grease pencil or some such before getting in, then get in and submerge yourself. And then mark the new water level on the tub while still submerged (the inaccuracy due to your fingers emerging from the water to mark the level should be negligible).
Then get out of the tub and confirm the water is still at the originally marked level (top it up if you sploshed out a pint or so in exiting the tub, for instance). Then start putting in additional measured amounts of water until the water level reaches your high-water mark that you made when you were immersed.
The total of those measured amounts of water will be the volume with mass equal to your own. More practical than trying to transfer measured amounts of water out of the tub while you’re still submerged in it (how long can you hold your breath, anyway?).
No. He specifically asked for an online calculator, and no one was able to find one. Instead people started giving unsolicited advice on other ways to handle the problem. He at first kindly told them it wasn’t useful, but then people not only repeated that advice, but came up with even less practical solutions. All the while people were snarking even though the original question had not been answered.
There are exactly two possible factual answers to the question in the OP: (1) Here is a website/program/method to calculate your approximate weight given your height and waist measurements (2) Nothing exists.
Everything else is people pretending like this was asked in IMHO, like he wanted advice rather than an answer to the question he actually asked.
Well, yeah. He said no scales in the OP. He asked an FQ question about some sort of calculator that would allow him to take measurements like his height and waist circumference and use that to estimate his weight.
If someone came in and said they needed to find a way to solve a math equation without using calculus, and everyone kept giving answers that involved calculus, the fault would clearly be with those who ignored the question.
That’s not to say you can’t say “there is no answer.” But it makes no sense to offer unsolicited advice. That’s always frustrating.
There are basically two reasons why someone might do that. The first is as a kind of intellectual exercise: can you solve this problem without using tool X. In this case, practicality can and should be thrown out the window. I suspect this is where the Archimedes-type solutions are coming from.
The second is that someone just doesn’t like that tool for some reason. But if that tool really is by far the best solution to the problem, it’s worth questioning why the OP is rejecting it. And solutions might include alternate ways of using the tool.
The OP seems to be in the latter category, but the entire setup is so weird that it’s hard to imagine that it’s not really in the first. I feel like for most adults, the question is like asking how to determine the color of your hair without a mirror. Of course you’re going to get silly answers.
If he’d started by saying that as an intellectual exercise, he wanted to know how to estimate his weight without scales, he would likely have gotten answers more along the lines of either formulas based on height and girth (or links to such) or things like the Archimedean options. And honestly, I thought the “look at these pictures, which are you most like” was fairly practical.
But no, he framed this question as an IMHO question. And his rejections of suggestions aren’t “I’m really interested in how to do this”, they are “no, I can’t walk into PetCo and use their scale. I’d be embarassed”. Again, he’s posting like this is IMHO.
In fact, I’m going to go poke the FQ mods and see if this shouldn’t be moved to IMHO, as you have convinced me that that’s why this thread is broken.
Do you visit your doctor for periodic, routine checkups? If so, you are weighed there. I bet if you called and asked for your last recorded weight, they could provide it.
Given the constraints of the OP and subsequent rejections of various methods, I think the OP has been answered about as well as it can be factually.
Also given that many of the responses are not practical and do not address the OP, and are also more along the lines of pointing out the difficulty in answering the OP than actually providing a useful answer, I think we’re done here.
