Weights and Measures, some calibration help

[Julian]

My prettier member of the crew recently bought a digital balance. It is quite a cheap one from the supermarket.

Aha I thinks, bottles unscrewed from the life jackets that are at home and weighed.

140g and 141g. This seems to correspond with the stamped weight of 137g on the bottles, does that sound correct? It is quite difficult to read the stamped lettering to be honest.

But how accurate are these cheap scales (balance)?

Now for the big online experiment, I wonder if those with accurate digital balances might weigh a few items for me as I don't have any old type weights from proper scales to prove this balance. I was thinking of stuff like a £1 coin, a £2 coin and so on. I am most interested in the lower down the scale readings, although this scale is good to 5kg apparently!

I know I could weigh a bag of sugar for example, or a jar of coffee, but they tend to be minimum weights don't they? Until I find some small calibrated weights in a jumble sale or such, I hope someone might as suggested weigh some common but standard weight stuff for me. The more the merrier, it will at the least have your wives looking on bemused...

ta in advance.

I'm sure you are aware of probably the most common use for these scales.

[sarabande]

The £1 coin has a mass of 9.5 g; the £2 coin has 12 g, and the 50p has 8 g.

So it will cost you £17.50 to weigh your Co2 cartridge


EDIT. I have just found that a 20p is 5g exactamento

yeah but it only has grammes so working out an 8th is going to be a bit long winded, or did you mean baking

thank you for that and fair doo's they measure exactly on these, not bad for cheapo scales from asda.
