Engineering Reference Tools
Quickly calculate percent changes, linear interpolations, and geometric properties. Handy reference tools for daily engineering tasks and data analysis.
Percent Change
Calculate the percentage increase or decrease between two values. Useful for analyzing trends, growth rates, and engineering tolerance changes.
Percent Difference
Determine the percentage difference between two experimental values relative to their average. Commonly used in lab reports and quality control.
Linear Interpolation
Perform linear interpolation to find intermediate values between two known points. Essential for reading engineering tables and sensor data calibration.
Circle Properties
Calculate the Area and Circumference of a circle given its Radius. Fundamental geometry tool for machining, design, and spatial analysis.
Golden Ratio A+B
Divide a length into two parts based on the Golden Ratio (1.618). Used in aesthetic design, architecture, and finding natural proportions.
