To convert lb/in² to pascals, we need to convert pounds (force) to newtons (force) and inches to meters. One pound is equal to 4.45 newtons, so we need to multiply by 4.45 N/1 lb. One inch is equal to 0.0254 meters, so we need to multiply by 0.0254 m²/1 in². Putting these conversion factors together, we get: (4.45 N/1 lb) x (0.0254 m²/1 in²) = 0.113 N/m² Therefore, the answer is D.
