Question says that a bookkeeper is posting to the accounts of a manufacturer of coffee. Their accounting software deals with weights in kilograms, but the company’s handwritten accounts state that they have produced 21,560 pounds (lbs.) coffee this month.
Now we have to find about what entry in kilograms should they put into their spreadsheet.
Basically they want to convert 21560 pounds into kilogram.
We know that 1 pound = 0.453592 Kilograms
Then 21560 pound = 0.453592*21560 = 9779.44352 Kilogram
Hence final answer is approx 9779.44 Kilogram.
