Well the good news for you is that at one tonne per sqkm = 1 gram per
square metre.

That should make your space shield much more practical- Hide quoted text -

Doh! You're right. I slipped a digit and a factor of 1,000! .

The plastics from which GBO is made are 1.2 metric tons per cubic
meter, so 1 gram per square meter is a thickness of 0.83 mm - that's

No, it's not.
There are a thousand litres in a cubic meter.
A thickness of a milimeter with an area of 1m has a volume of one litre,
which has a weight of one kilogram.

Yes, I listened to you and was confused! lol. So, is your original
point correct or not?

<sigh>

Well, lets figure it out - haha..

1000 gram = 1 kg
1000 kg = 1 tonne

1,000,000 grams = 1 tonnes

1 mm = 1/1,000 meter
1 um = 1/1,000 mm
1,000,000 um = 1 m

At 1.2 gams per ml or 1.2 tonnes per cubic meter for the types of
plastics used for GBO then layers 1 square meter in are are;

830 nm = 1 gram per sq meter
830 um = 1 kg per sq meter

haha.. SO, MY ORIGINAL NUMBERS ARE THE CORRECT ONE!

And your original point in error.

Umm - you initially claim that .83mm is one gram per square meter.
In this post you correct that, and agree with my point.

I think you may be the one that is confused.
