some times I weigh my self at home, some times at the gym, sometimes at the other gym and I get a different reading. Do you trust these scales, what's a good way to make sure they are at least some what close to being accurate.

It may depend on the scale. Mine is analog (non digital) and you can adjust the zero reading by moving a small lever. I'm not sure you can adjust a digital scale meant for home use. But you might look at the literature that came with it.

Here's what I did with mine. First get a weight you are fairly confident is accurate. I chose a 25lb weight from my set. Place the weight on the scale and adjust the reading. Then I stood on the scale and read my weight. Now pick up the weight and stand on the scale again. Does the new weight read correctly? I've done the same test with a 50lb weight.

If it doesnt' I don't know what to do. Get a new scale? They're fairly cheap. Mine worked.

Side note: The zero reading (no weight) on my "adjusted" scale is now 3lb. To me that means my scale is not going to work well below that 25lb reading. It is possible there are inaccuracies in the readings I am using. Does it matter if I'm off by a couple of pounds? Not to me. Does it matter to you? That's for you to decide.

I would recommend using one scale and making sure it is always calibrated. This way, you know for sure what your readings always are. Here are some tips for calibrating your scale: Tips to Calibrate Your Scale - Weight Loss Answers Online

Always weigh yourself in the morning when you first wake up, and after you've been to the bathroom, and before you eat or drink anything.

If you weigh yourself at various times during the day, your weight will fluxuate depending on how much food, water, and body waste your body contains at that moment.

So it's best to weight yourself when it contains the least amount of food, water, urine, etc.

This is my routine as well. I then write it on the calendar when I get my coffee, easy to spot any "trends" that way.

Accuracy doesn't much matter - consistency does. Scales measure differently from each other, because of the technology they use. Use only 1 scale and the same time of day, each time.

If you used a balance all the time, it would be consistent and accurate.

Ok so I went to the gym last night put a 10 kg weight on it got about 25lbs (the scale didn't zero out stayed at about 5lbs, and didn't appear to have a calibration dial on the back) and it read 265lbs.
I went home did the same thing with a 10lb weight and it read 10lbs, I stepped on the scale and it read 285+lbs, but I noticed that scale at home has always given me a consistent reading around 280.

You should point that out to your gym and ask the last time it was calibrated. All scales have a margin of error too. Its usually in the details of the model info. You calories needs only change when you go over the 10lbs window. So your gym really needs to get that scale fixed. It may be getting used more than they realize and they should up the maintenance schedule on it or replace it.

The best way to get accurate readings is to weigh yourself on the same scale. Actually, I should say "consistent" readings.

A while back I switched from an analog scale to a digital scale. I ran them side by side for a couple of weeks. The analog scale read 3# lighter than the digital scale (for me a large % of weight). But, it was consistently 3# lighter for the period of time that I weighed myself on both scales, so even though I don't know if one or the other is "correct", I do know that the new one is consistent.

Default best scale

I plan to get a detecto balance beam scale. They are expensive but the best.
