There is no straightforward conversion. An image that has (for example) 800 x 600 pixels needs to represent that many picture points. Without data compression, each picture element needs about three bytes (depending on the color depth); however, formats such as JPEG do use data compression, more precisely, lossy data compression - and the factor by which data is reduced with data compressed varies, depending on the image quality. That is, in lossy data compression, more compression means less quality.
To convert a video to the yuv420p pixel format using ffmpeg, you can use the following command: ffmpeg -i inputvideo.mp4 -pixfmt yuv420p outputvideo.mp4 This command will convert the input video to the yuv420p pixel format and save it as the output video in mp4 format.
To calculate the calibration factors for converting pixels to SI units, you first need to determine the physical dimensions of a known object in the image and its corresponding pixel dimensions. Measure the number of pixels that span the known object's width or height, and then divide the actual size (in meters) by the pixel measurement to obtain the calibration factor (in meters per pixel). This factor can then be applied to convert other pixel measurements to SI units by multiplying the pixel count by the calibration factor.
Kilobyte
There are exactly 1024 megabytes (MB) in 1 Kilobyte (KB).
There is no definite answer. It depends on the pixel density of whatever program you are trying to convert from.
there are 50000 gigabytes in a kilobyte
a kilobyte is 1024 bytes
There are 8192 bits in a kilobyte.
1 kilobyte (kB) = 1000 bytes
1 KiloByte = 1 KB
You will need to have an idea of the resolution of the picture to change this through your photo software.
It is the same. 1 dot is also 1 pixel.
