`Delta x = x_2 - x_1`

Enter a value for all fields

The Delta x calculator computes the difference between two lengths or distances (x₂) and (x₁).  

INSTRUCTIONS:  Choose units and enter the following:

• (x₁) Length 1
• (x₂) Length 2

Delta x (Δx): The calculator returns the difference in meters.  However, this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The formula for the change in distance is:

     Δx= x₂ - x₁

where:

• Δx is the difference in time between the two reference lengths.
• x₁ is length reference point one.
• x₂ is length reference point two.
