## Linear Interpolation Value Calculator

**Linear Interpolated Calculator**

Linear interpolation calculator is an online analytical goemetric calculator for calculating an unkown value lying between two known co ordinates. Generally linear means straight and interpolation means to find a point within two given points and exrapolation means findig outside the points. Linear interpolation is also abbrevated as lerp. This calculator accepts x1,y1 x2,y2 and the target x coordinate as input values and provides the output y value which is lying between the two given co ordinates. Linear interpolation always finds its use in many applications including statistics. for example if we have a table of values and if we want to close a gap in it by finding intermediate values, then we go for linear interpolation. Use this online linear interpolation calculator to find instant results.

### Linear Interpolation Value Calculation

Formula used in Linear interpolation:

Y = ( ( X - X1 )( Y2 - Y1) / ( X2 - X1) ) + Y1

Where,

X1,Y1 = First co-ordinates,

X2,Y2 = Second co-ordinates,

X = Target X co-ordinate,

Y = Interpolated Y co-ordinate.
