If you want to go into that level of detail to compare relative military spending, there are going to be other factors to consider. Its a huge rabit hole trying to normalize data between countries with entirely different currencies, economics, political structures, etc.
For example, the US has the benefit of printing money in ways that other countries don't. I'm not even sure how you'd adjust military spending to account for the benefit of printing fiat as the world reserve currency, its more like you're playing a game that no other country is allowed to play.
