Download time estimate
Estimate an ideal transfer duration from decimal file size and a stated link rate.
Video file size estimate
Estimate payload size from combined bitrate and duration.
Uncompressed audio size
Estimate PCM payload size from sample rate, bit depth, channels and duration.
Raster memory estimate
Estimate raw raster pixel-buffer memory without file compression.
Image print size
Calculate physical print dimensions from pixel dimensions and a selected density.
Screen pixel density
Calculate diagonal pixel density from screen resolution and physical diagonal.
Frame duration calculator
Find nominal frame time from a frames-per-second rate.
Recording storage duration
