How to Use the Length & Height Converter

1. Enter the value — type the number you want to convert into the "Convert From" box.
2. Select units — choose your starting unit and the unit to convert into; the math runs instantly.
3. Dual height mode — pick "Foot (ft)" and a second "Inches" box appears so you can enter a human height like 5 ft 10 in, and it even accepts fractions such as 10 1/2.
4. Bi-directional typing — type in either box. Entering a value on the right reverse-calculates the left automatically.
5. Precision & fractions — set decimal places, or tick "Show inches as fraction" for construction-friendly results like 5' 6 7/8".
6. Live matrix — see your value in every major unit at once, and copy the whole table in one click.
