Originally, exactly as much as a volume of water equal to the cube of the hundredth part of the metre, at the temperature of melting ice. I don't find that terribly helpful. Not many did. That's why, in 1889, the mass of the kilogram was redefined as being equal to the IPK.
Boiling water is also an effective poison ivy killer. If the area where you will be killing poison ivy has no other plants you wish to keep, pour boiling water over the poison ivy plant. Boiling water will kill any part of a plant that it comes in contact with, so be careful using this around desirable plants.
Oh man! Poison Oak, Ivy, and Sumac are awful. Poison Ivy is bad, Poison Oak is worse, and Poison Sumac is awful. To get rid of Poison Ivy or Oak get a Steroid shot or cream â¦(personally I prefer the cream). Spread the cream onto your rash 2-4 times a day and as many days as the Dr. prescribes. To get the cream or shot go to your doctors.
