The eotvos is a unit of gravitational field gradient that was used in conjunction with the older centimetre–gram–second system of units (CGS). The eotvos is defined as 10−9 galileos per centimetre. The symbol of the eotvos unit is E.
In SI units and in CGS units, 1 eotvos is 10−9 second−2.
The gravitational gradient of the Earth, that is, the change in the gravitational acceleration vector from one point on the Earth's surface to another, is customarily measured in units of eotvos.
The eotvos unit is named for the physicist Loránd Eötvös, who made pioneering studies of the gradient of the Earth's gravitational field.
