The conversion between international units (IU) and grams (gm) depends on the substance being measured, as different substances have different conversion factors. For example, 1 IU of vitamin D is approximately 0.025 micrograms (mcg), while 1 IU of insulin is around 0.0347 mg. To convert 1,000,000 IU to grams for a specific substance, you would need to know the specific conversion factor for that substance.

Balestra. It is not really a jump in place, for the body should cover some forward distance, even more than the lunge that follows. When the balestra is executed correctly, the body does not hop up in the air(wasted movement) but springs forward in a way that looks like a regular lunge to the opponent. But instead of the trailing leg staying back, it is immediately brought up together with the lead foot. If the opponent has evaded this first attack, he might not be ready for the lunge that immediately follows.
