About these units
Sun's Mass (M☉)
The Sun's mass, approximately 1.9885 × 10³⁰ kilograms, dominates the solar system, comprising 99.86% of all its mass. Solar mass controls planetary orbits, defines the structure of the heliosphere, and fuels stellar fusion reactions that sustain life on Earth. Astronomers use the solar mass as a comparative unit for other stars, star clusters, and black holes, making it one of the most important astronomical constants.
Poundal (pdl)
The poundal is the unit of force in the foot–pound–second (FPS) system, defined as the force that accelerates a one-pound mass at one foot per second squared. Although a force unit, it interacts with mass units in engineering contexts similarly to inertial mass units. Historically, poundals appeared in older physics textbooks and engineering references before the widespread adoption of SI units. Their use has declined dramatically, but they remain part of the history of classical mechanics education. The poundal exemplifies how many different systems attempted to rationalize force, mass, and acceleration before the international community converged on the SI newton.
