I'm a Fish!
I was reading an article today where a diver suggested that using metric tables or a computer set to a metric depths setting was safer then using an imperial depth table. I personally disagree in that when considering table or computer use no table can predict when and under what conditions a diver will be subject to or worst yet get DCS. You thoughts?
 
Metric depths are either rounded up or down in larger increments. So in some cases it may be safer and in others more dangerous! The metric recreational max depth is deeper than the Imperial max depth, so I chose Imperial as safer, just to pick one!
Seems silly!
 
I don't see how it might relate to safety?
 
Should the question in your poll ask which one is safer? Or should the answer choices be yes or no? The answers don't match the question.
 
Like with many "standards", the standardization itself is more important than which one you pick. The safest system to use is the one that both you and your buddies are familiar with.

Otherwise, I don't see how the choice of units has any relevance to safety.

Option #3: Doesn't make any difference.
 
I use metric and find it safer for me, only because when I have used an imperial dive computer I sit there for 10 mins getting my diving depth, divinding it by 3 etc and turning it into metric numbers.

I do not see how it makes a difference at all. Use what you are comfortable with and go from there.
 
The only difference I can see would be in the rounding...the interval in metric tables is 9ft while it´s 10ft in imperial, maybe that results in more "accurate" NDLs...of course 1ft either way won´t be what gets you hurt anyway...the safest would be the one you´re most comfortable with...the "best" would be metric ;)
 
The only real safety issue I see regarding units of measurement might be that it's safer to stick with the system you are used to. Big difference if you think you're diving at 60 feet and instead are at 60 meters...
