please fucking capitalise units properly , the most valid interpretation of "mbps" is millibit picosecond which is invalid anyway (should be femtobit second or fb s) and also not a unit of any kind of speed , not that you are asking about speed but likely bandwidth , but also in this specific case , ignoring that you use this stupid per construct , leaving it to interpretation which letter is meant to be capitalised and which lower case leaves megabits per second (Mb s^(-1)) and megabytes per second (MB s^(-1)) (of course milibits per second and milibytes per second are also units of bandwidth) , and also because bits and bytes are involved , are you using the mega- prefix per SI or , I would argue incorrectly , per JEDEC (as in 1 KB = 1024 B ) , I don't know because you have shown a complete disregard for units and all they represent , for everyone who takes the time to understand , learn and properly use prefixes to convey a specific meaning , in a way that cannot be misinterpreted . You may not think this is important because "oh Lily you understood me anyway" and ? you have shown a complete disregard for all that anyone with a computer science degree should stand for , shown no intention to properly understand how the more and more computerised would around us works and for what ? so that your fingers can use a few less calories , putting of the heat death of the universe by an unimaginably irrelevant amount , which you will unknowingly spend anyway when you hear a bird sing across the road , is that really worth it to you ?
