What it measures
India's GDP converted to international dollars using purchasing power parity (PPP) rates, which adjust for differences in price levels across countries — making cross-country GDP comparisons meaningful.
How it is calculated
IMF applies PPP conversion factors (derived from the International Comparison Program's price surveys) to India's GDP in rupees, expressing it in a common "international dollar" unit that equalizes purchasing power.
