What is the dilution rate for Roundup concentrate in liters?

One liter (two pints) in a sprayer and five liters (one gallon) in a watering can are the dilution rates for Roundup concentrate in liters. The amount of the concentrate may vary from 20 milliliters (0.68 fluid ounces) for annual weeds (annual meadow-grass, chickweed, speedwell) and areas that will not be vegetated to 30 milliliters (1.01 fluid ounces) for conches, grasses and perennial broad-leaved weeds (bindweed, dandelions, docks, thistles) and 40 milliliters (1.35 fluid ounces) for bracken, brambles, nettles and scrub. Regardless of the concentrate amount or the garden tool, the dilution will treat only an area of 20 square meters (215.28 square feet).
