Formula help

I was just at this web site

And it shows you the formula for finding out how mutch Video RAM will be used to display moniters.

Ok so I get Herizantle REZ   X    Verticale REZ   X   Bit Depth =   Video RAM in Bytes or is it Bits    then you Divide by something to get MB.

And this is what your video card will use per sec  to display and inage on screen.

I did not get what you Divide by to  get Mega Byte   and first off is it giving us it in Bytes or Bits.
Thanks

Bits.

After the division, the answer will be in megabytes.

From the article: Why divide by 8,388,608? Because video cards advertise their video memory in megabytes, and 1MB has 8,388,608 bits (8 bits in a byte times 1024 bytes in 1 kilobyte times 1024 kilobytes in 1MB).

So it's Herizantle   x Verticale   x   Bit Depth  =   Memory in Bits   then take that and Divide by  8,388,608  is that it  do I have it now??

Yes.

1) Horizontal x Vertical x Bit depth = Memory in bits.

2) To convert to megabytes (MB): Divide the answer from 1) by 8,388,608 [(8 bits/byte)(1024 bytes/kilobyte)(1024 kilobytes/megabyte)]
