Diagonal Formula:
| From: | To: |
The diagonal of a square or rectangle can be calculated using the Pythagorean theorem. For any rectangle, the diagonal forms the hypotenuse of a right triangle with the length and width as the other two sides.
The calculator uses the formula:
Where:
Explanation: The calculator first converts both measurements to inches, performs the calculation, then converts the result back to feet and inches for easier interpretation.
Details: Calculating diagonals is essential in construction, carpentry, graphic design, and many other fields where precise measurements are required for fitting objects into spaces or creating accurate layouts.
Tips: Enter the length and width in feet and inches separately. The calculator will automatically convert these to a common unit (inches) for calculation, then convert the result back to feet and inches.
Q1: Does this work for squares as well as rectangles?
A: Yes, the formula works for both squares and rectangles. A square is simply a special case of a rectangle where length equals width.
Q2: Why convert to inches first?
A: Converting to a single unit (inches) makes the mathematical calculation simpler and more accurate before converting back to the preferred mixed-unit format.
Q3: How precise is the calculation?
A: The calculation is mathematically precise. The result is rounded to two decimal places for the inches portion for practical measurement purposes.
Q4: Can I use this for metric measurements?
A: This specific calculator is designed for feet and inches. For metric measurements, you would use a similar calculator that works with meters and centimeters.
Q5: What if I have measurements in decimals instead of feet and inches?
A: For decimal feet, you can enter the whole number part in feet and the fractional part converted to inches (multiply by 12).
