Angle of Depression with stated conventions, validation and a worked example.
Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Measured downward from a horizontal line; flat local geometry.
Example Calculation
- Vertical drop: 3 units
- Horizontal distance: 4 units
A vertical drop of 3 over horizontal distance 4 gives approximately 36.8699°.
Frequently asked questions
How do I use this calculator?
Enter vertical drop, horizontal distance. The result updates automatically. Use Reset to restore the example values.
What method does it use?
θ=atan(vertical drop/horizontal distance). Measured downward from a horizontal line; flat local geometry.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
