In the Taiko Kenchi (land surveys conducted by Hideyoshi TOYOTOMI), the method for ranking rice paddies was to reduce 2 To (36 liters) when the rank of the rice paddy is downgraded by one (also known as "Nitokudari," literally meaning "reduction of Two To"); rice paddies that produced 1 Koku and 5 To (about 270 liters) was ranked as high grade, those that produced 1 Koku and 3 To (about 235 liters) as medium grade, and those that produced 1 Koku and 1 To (about 198 liters) as lower grade; while the standard for residential areas was to be 1 Koku and 2 To (about 216 liters), other fields known as 'mihakarai,' such as bottom-ranked rice paddies, fields and riverside fields were left to the discretion of the person in charge of the land survey.
太閤検地においては、上田を1石(単位)5斗、中田を1石3斗、下田を1石1斗としてランクが1つ落ちるごとに2斗ずつ下げる方法（2斗下り）が採用され、屋敷地は1石2斗を基準とすること、下々田・畠・河原などについては「見計い」とされ、検地担当者の裁量によるものとされた。
