Estimating remaining length of PLA reel?

I assume that my first reel of 1.75 mm PLA is close to some standard.

I don't see it specified on the site but does anyone know the approximate weights of a full and empty 1 kg reel please? I can then weigh it on my kitchen scales to estimate the remaining length. Wouldn't like to run out before a print finishes.

https://www.dropbox.com/s/zyhhnqlsvh0w2ta/SecondCrealityPLA.jpg?raw=1Thanks for the fast reply. My second reel from Amazon has just arrived and its total weight (including the plastic sealing) is 1230g. Say 1220 spool + 1kg filament, so 220g of black PLA. As you see, it looks a heavier reel:

So I'll guess 190g spool weight for the present one. Its total weight of 440g, implying I have about 250g left. Does that look reasonable from the screenshot?

Pity the Ender 3 V2 doesn't accumulate usage by either weight or length. Do any home user 3D printers do that?
