Big Dipper, ten sho (vol), sake dipper, dots and cross radical (no. 68)
斗 centers on a dipper or ladle: a tool for scooping liquids like sake, and by extension a unit of volume (roughly 18 liters). The Big Dipper constellation is named for its dipper-like shape, and the radical sense refers to the same dipper shape used as a component in other characters.
斗 is a pictograph of a ladle or dipper with a handle. The modern form retains the basic shape: a cross-like handle and a scooping vessel.
The two dots at the top are the contents being scooped, the cross is the handle, and the lower strokes form the dipper's bowl. Picture a sake dipper lifting liquid: 斗 is a dipper.
For ト, imagine a toe dipping into a sake dipper: toe -> ト, and the dipper scoops up the sake.
