turf junkie, it sounds as if you are dealing with a product like metsulfron ("Manor") or something similar. It is very difficult to measure such small quantities of a solid product even with the measuring device supplied. My best suggestion would be to weigh one ounce of the product and try to get the quantity into a rectangular shape. Then try to divide that into 20 little 'squares' and then use one of these in the little sprayer. Tedious maybe, but you show a commendable persistwnce for applying chemicals responsibly and you will most likely go the 'extra distance' to achieve this very worthwhile objective. At the risk of 'preaching to the choir' I may add that the correct weight or volume of the a.i for the area to be treated is the first consideration; next is the amount of carrier (water) to uniformly cover the area.

Ken, interesting. I guess the US is slowly moving to the metric system. Personally IÂm a transition child who grew up with the Imperial system and then had to learn the Metric system in later grade school. I understand the logic behind us switching for international trade reasons (most of the world is Metric) but old habits die hard, I still convert Kilometers to Miles, Celsius to Fahrenheit etc. Zeuspaul, thank you for checking. Yes, I used a good carpenters square to measure the dimensions. Your input helped tip me to go ahead with my purchase. Very much appreciated. Bill

You may have the answer in your household, but don't know where to find it. Some dictionaries include a conversation table either in the back of the book, or under the word, "weights and measure". Many math text books have a conversion table. Some tape measures and scales have dual scales.
