• Answer:

  On tax forms, the change is usually rounded down to the amount in pounds only when figuring out what you owe the government. When people list the salary they were paid at previous jobs on applications, they usually round up or down a little. Like if you were paid 20, 350 pounds a year, you would round up to 25,000 pounds a year or down to 20,000 pounds a year. People usually round their weight up or down a little too, rather that use the exact weight figure.
