how do i change 30.50 in^2 to mm^2
my conversion sheet says its
1 inch =25.4mm
So i did the following:
30.50in^2 * 25.4mm =774.7mm
but i don't know if i should square it or not?.. im confused please help
1 inch =25.4mm. That is right.
But when squaring, you have to square both the units _and_ the numbers, so
1 inch = 25.4 mm
(1 inch)^ = (25.4mm)^2
(1^2) inch^2 = (25.4^2) mm^2
1 in^2 = 645.16 mm^2
Or think of it this way:
Draw a 3-inch line. That's 3 inches.
Now make a square from it with 3 inches on each side. How many square inches is that?
To convert square inches (in²) to square millimeters (mm²), you need to use the conversion factor between inches and millimeters.
Since your conversion sheet states that 1 inch is equal to 25.4 millimeters, you need to square this value to convert the area. Here's how you can do it:
1. Start with the given area in square inches: 30.50 in².
2. Multiply the given area by the conversion factor to convert to square millimeters.
Conversion factor: (25.4 mm/inch)².
30.50 in² * (25.4 mm/inch)² = 30.50 * (25.4 * 25.4) mm².
3. Calculate the result:
30.50 * (25.4 * 25.4) = 30.50 * 645.16 ≈ 19703.964 mm².
Therefore, 30.50 square inches is approximately equal to 19703.964 square millimeters.
