# Percentage errors!! watch

1. I need to know the percentage error of my digital thermometer as the percentage error changes as the temperature increases???

1 dp digital thermometer

0.1 degrees
98.7 degrees
99.5 degrees

it is a hanna digital thermometer which is highly accurate but need to work out percentage error for a task.

I did: 0.1/0.1 x 100% = 1%

99.5 / 0.1 x 100 = 0.1%

are they allowed to be different??? have I calculated it right?

thanks
