1000 notes at 1 g and 100 coins averaging 5 g total 1.5 kg.
Frequently asked questions
How do I use this calculator?
Enter notes, mass per note, coins, average mass per coin. The result updates automatically. Use Reset to restore the example values.
What method does it use?
mass=notes × note mass+coins × average coin mass.. Mass per piece must match the actual currency and denominations. Bundles, bags and containers are excluded.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
