1. Count the marks to the
RIGHT of the zero line.
2. Numbered marks are grams.
3. Small hash marks are tenths (.1) of grams
This balance shows 4 grams
This balance shows 7 tenths or .7 g.
So far we have:
4.7 grams

When the zero mark is
between tenth marks on the dial, you then read the
hundredths scale.

You must look straight on at the dial
to match lines correctly. These two marks seem joined the
