PPG

PPG commonly refers to PPG Industries, an American multinational that specializes in paints, coatings, and specialty materials. The company traces its origins to 1883 as the Pittsburgh Plate Glass Company and later adopted the shortened name to reflect diversification beyond glass. Headquartered in Pittsburgh, it operates globally with a portfolio that includes automotive finishes, architectural coatings, industrial and packaging coatings, and specialty materials for aerospace and electronics, along with color and design services. PPG is publicly traded on the New York Stock Exchange under the ticker symbol PPG and is a member of the S&P 500. The company emphasizes sustainability, research and development, and strategic acquisitions to expand its product lines.

In medicine and digital health, PPG stands for photoplethysmography, a noninvasive optical technique that detects blood volume changes in the microvascular bed of tissue. It typically uses a light source and a photodetector to estimate heart rate, blood oxygenation, and other cardiovascular parameters, and is commonly incorporated into wearables and clinical monitors.

In sports statistics, PPG stands for points per game, a measure of scoring productivity. It is calculated by dividing total points by the number of games played and is used to compare players or teams across seasons and leagues.
