What's a 3" (diagonally) screen in mm?? - SOLVED

[blurredvision]

I'm looking to convert what a 3" screen is to mm. If a screen is 3" diagonal, what does that make it height and length wise in mm? TIA

 

[mugs]

3" = 76 mm. If the aspect ratio is exatly 4:3, the width would be 60mm and the height would be 45mm. I think

1 inch = 2.5 cm

I'll give you a hint:

76.2² = (4x)² + (3x)²

Solve for x, multiply by 4 & 3.

x = 15.24

W = 60.96 mm
H = 45.72 mm

WTF? LOL I probably could've done this when I was high school a few years back, but not now. My math skills have gone the way of the dodo.

Since others decided to play nice I solved it for you.

Thanks Viper. Much appreciated.

 

[FrustratedUser]

Diagonal = SQRT(X^2 + Y^2)
Aspect ratio = 4:3
1" = 25.4mm

Now solve for X and Y with 4X=3Y.

DOH! To late.
