Examples: It won't take *that* long to download this 650MB cd image over Mom's 33.6Kbps modem, will it? I can just let it run all night. % ucalc "650MB/33.6Kbps" 1.834 day What's the throughput for random 8KB reads, using a hard disk with 20MB/sec transfers and an average access latency of 15ms? % perl -MMath::Calc::Units=readable -le 'print foreach (readable("8KB / (8KB/(20MB/sec) + 15ms)"))' 532.3 byte / millisec 1.785 gigabyte / hour 42.83 gigabyte / day 519.8 kilobyte / sec 30.46 megabyte / minute Note: ucalc is a thin wrapper script that pretty much does what the one-liner above does.
