How far is the horizon? How far until the earth curves?

Your height:

Feet

Inches

Feet Above Ground (~10 feet per floor)

**In a tall building or hotel? Multiply floor # by 10. Then subtract 10.*

**{{ (1.2246 * (squareRoot((inputUserHeightFeet + (inputUserHeightInches / 12) + inputFloorHeight)))) | number : 2 }}**miles away. At this point, the earth is no longer visible because of the curve.

**Horizon Distance Formula**

*Distance (in miles) = 1.2246 * √height*

You are {{ inputUserHeightFeet }}' {{ inputUserHeightInches }}" and {{ inputFloorHeight }} feet above ground.

Height (in feet @ eye level) = {{ ((inputUserHeightFeet + (inputUserHeightInches / 12) + inputFloorHeight)) | number : 2 }}

#### How Does It Work?

A user inputs their height in feet and inches. Also, they input their feet above the ground. The inches in height are divided by 12 and added to the height in feet of the person. Next, you add that to the amount of feet above ground. This is your total height. Then you will find the square root and multiply it by 1.2246.

If you are stranded and swimming in the ocean, the height of your eyes will only be 6 inches to 1 foot. This will only allow you to see about 1 mile away. People will likely see you before you see them.
