Tool description
A scientific calculator that determines Earth's curvature effects, horizon distances, and how much of distant objects is hidden by the planet's curvature. Essential for surveying, navigation, photography, and understanding perspective over long distances.
Features
- Multiple Unit Support: Calculate in kilometers, miles, meters, and feet
- Observer Height Consideration: Accounts for observer elevation above ground
- Three Key Calculations: Curvature drop, horizon distance, and hidden object height
- Scientific Accuracy: Uses Earth's actual radius for precise calculations
- Real-time Results: Updates calculations instantly with input changes
- Unit Conversion: Seamless conversion between metric and imperial units
