But this battle was in China where isk x real money prices are different, apparently the PLEX (the only formally recognized way of turning real money into isk) is a lot more expensive in-game over there, thereby depressing the real-money value. According to [1], isk is worth 1/6th in the Chinese server, meaning the total damage was around $110,000.

Note that this is on the Chinese server - so I don't know if the USD translation is the same.
Most of the time it's (USD per 'plex' divided by ISK to sell a plex on the market) to get the price in USD per ISK. a 'plex' is a 30 day pass to play the game, and is also an in-game item suitable for sale.
The Chinese server is totally distinct from the RestOfWorld server - no shared space / market / anything. So I have no idea what the price of ISK is on the Chinese market, or if they even support that kind of trade.
Doesn't it say 26T which is $706,675.75 USD?
`With the bar set at 11 trillion ISK in damages during the battle of B-R5RB on Tranquility in January, Serenity went ahead and smashed that record, almost doubling the ISK value of hulls destroyed at an astonishing 26 trillion ISK worth of damage.`
is roughly $700,000 USD.
Edit: updated the ISK value thanks to comments.
