Abstract
This scientific article is focused to construction of formula for transformation of the differential leveling observation between two benchmarks to the difference of geopotential numbers to serve an adjustment of state height network in the geoid -based vertical reference system. This article also shows that when mean value of normal gravity acceleration corresponding to benchmark has the unit of kGal, difference of geopotential numbers and Earth potential will have the unit of kGal.m. On this occasion error limits gave on Instruction of the state height network will not change values, only their units will be changed from mm to kGal.mm, from mm/ 1 km to kGal.mm/1 km. Analogically, weight of the difference of geopotential numbers of leveling line will be equal to weight of the differential leveling observation of that leveling line.
