Emmi Posted July 25, 2013 Report Share Posted July 25, 2013 It depends on how many divisions are on the measuring tool. Some measuring cylinders have a lot of tick marks, and others just one every milliliter, and same with the others. Can you give us a little more information? 1 Reply Link to post Share on other sites More sharing options...

Emmi Posted July 25, 2013 Report Share Posted July 25, 2013 With a 1 mL or a 1 degree centigrade tick mark, the uncertainty is to the tenths place. With a 0.5 mL or degree centigrade tick mark, the uncertainty is to the hundredths place. 2 Reply Link to post Share on other sites More sharing options...
