REMEMBER! If you are substituting yarn in a pattern, it is the total YARDAGE that is important NOT the weight of the yarn!

For example, if the pattern calls for 10 50-g/1.75oz (120m/131yds) balls of wool, you will need to buy at least 10 x 120m/131yds or 1200m/1310yds of the yarn you wish to use in order to have enough for your pattern.
