The image above represents bourger correction.

To compute for bourger correction, three essential parameter are needed and these parameters are **Gravitational Constant (G), Density of the Material (ρ) **and **Height at Measured Point above Sea Level (h).**

The formula for calculating bourger correction:

δg_{B} = 2πGρh

Where:

δg_{B} = Bouguer Correction

G = Gravitational Constant

ρ = Density of the Material

h = Height at Measured Point above Sea Level

Let’s solve an example;

Find the bourger correction when the gravitational constant is 6.67E-11, the density of the material is 24 and the height at measured point above sea level is 18.

This implies that;

G = Gravitational Constant = 6.67E-11

ρ = Density of the Material = 24

h = Height at Measured Point above Sea Level = 18

δg_{B} = 2πGρh

δg_{B} = 2π(6.67e-11)(24)(18)

δg_{B} = 2π(2.88144e-8)

δg_{B} = 1.81e-7

Therefore, the **bourger correction **is **1.81e-7 mGal.**

**Calculating the Density of the Material when the Bourger Correction, the Gravitational Constant and the Heigth at Measured Point above Sea Level is Given.**

ρ = ^{δgB} / _{2πGh}

Where;

ρ = Density of the Material

δg_{B} = Bouguer Correction

G = Gravitational Constant

h = Height at Measured Point above Sea Level

Let’s solve an example;

Find the density of the material when the bourger correction is 22, the gravitational constant is 6.67E-11 and the height at measured point above sea level is 15.

This implies that;

δg_{B} = Bouguer Correction = 22

G = Gravitational Constant = 6.67E-11

h = Height at Measured Point above Sea Level = 15

ρ = ^{δgB} / _{2πGh}

ρ = ^{22} / _{2π (6.67e-11)(10)}

ρ = ^{22} / _{2π x 6.67e+11}

ρ = ^{22} / _{4188760000000}

ρ = 5.25e-12

Therefore, the **density of the material **is **5.25e-12.**

**Calculating the Height at Measured Point above Sea Level when the Bourger Correction, the Gravitational Constant and the Density of the Material is Given.**

h = ^{δgB} / _{2πGρ}

Where;

h = Height at Measured Point above Sea Level

δg_{B} = Bouguer Correction

G = Gravitational Constant

ρ = Density of the Material

Let’s solve an example;

Find the height at measured point above sea level when the bourger correction is 32, the gravitational constant is 6.67E-11 and the density of the material is 10.

This implies that;

δg_{B} = Bouguer Correction = 32

G = Gravitational Constant = 6.67E-11

ρ = Density of the Material = 10

h = ^{δgB} / _{2πGρ}

h = ^{32} / _{2π (6.67e-11)(10)}

h = ^{32} / _{4188760000000}

h = 7.639e-12

Therefore, the **height at measured point above sea level **is **7.639e-12.**
