10 × 10 graph paper with tenth-of-an-inch squares, medium lines every half inch and heavy lines every inch — the classic paper for plotting data precisely, because each heavy square is one inch divided into a hundred cells.
Each small square is 0.1 of the heavy square, so you can plot values to one decimal place without estimating.
Yes — millimeter graph paper has 1 mm squares with 5 mm and 1 cm lines.
Measure 10 squares with a ruler. At 100% scale, 10 squares of 1/4 inch measure exactly 2.5 inches, and 10 squares of 5 mm measure 5 cm.
