An IV container for precise measurement and dispensing of fluid contained in the IV container. This IV container has an upper fluid-containing portion to contain and measure a first quantity of fluid. The upper fluid-containing portion has a first cross-sectional area, and a first plurality of fluid measurement markings along a side of the upper fluid-containing portion that represent measurement units of a first size. A lower fluid-containing portion is in fluid communication with the upper fluid-containing portion, and can contain and measure a second lesser quantity of fluid. The lower fluid-containing portion has a second cross-sectional area that is less than the first cross-sectional area. The lower fluid-containing portion has a second plurality of measurement markings along a side of the lower fluid-containing portion that represent measurement units of a second size that's smaller than the units of the upper fluid containing portion, and therefore provides enhanced measurement precision.
