The Weight Calculator helps you calculate the weight of an object using the simple physics formula W = m × g, where W is weight, m is mass, and g is gravitational acceleration. Just enter the mass in kilograms (kg) and the gravitational force in meters per second squared (m/s²), and the calculator will instantly display the weight in Newtons (N). By default, gravity is set to 9.81 m/s² for Earth, but you can change it for other planets. This tool is accurate, mobile-friendly, and ideal for students, teachers, and physics enthusiasts who need quick weight calculations online.
