More Math Help Needed Please.
I'm struggling to work out the GSM of some card I have promised someone.I weighed 10 sheets to get a more accurate reading, and that was 160gr.
One sheet is 210mm by 300mm, which I think converts to 0.06 of a square metre, and weighs 16 gr.
How on earth can I work out the grams per square metre please.
Totally lost it here this afternoon trying to get the correct answer.
Grateful for any help, thanks.

I agree with FF.
Rounding the answer to that calculation yields 250 gsm which is, reassuringly, a commonly sold card thickness . e.g. here:

I think Buenchico's figure of 250 will be right. Based on that figure and 1/16th of a square metre the weight of each card would be 15.625g, so the weight of the 10 ferlew weighed should have been 156.25g which could have been read as 160g with a bit of rounding, slight inaccuracy of the scale, maybe dust on the card and and possibly some parallax error
