What is Weight?
Weight is the force exerted on an object due to gravity. It depends on both the object's mass and the gravitational acceleration. Weight = Mass × Gravity.
Τύποι Υπολογισμού
Convert Weight Units
Enter a weight value and choose from/to units (kg, g, lb, oz, stone, ton, etc.) to get the converted value.
Calculate Weight from Mass
Enter mass and gravity (e.g. 9.80665 m/s² for Earth). Result is force in Newtons or in lb/kg-force.
Calculate Mass from Weight
Enter weight (force) and gravity to get mass in kg, g, lb, or oz.
Weight on Planets
Enter your weight on Earth and select a planet (or Moon/Sun) to see your weight there. Your mass stays the same; only gravity changes.

Weight Units
Μετρικός: kg, g, mg, t
Αυτοκρατορικός: lb, oz, st, ton
Αλλος: ct (carat), N (Newton)

Weight from Mass:
W = m × g
Mass from Weight:
m = W / g
Where: W = Weight (N), m = Mass (kg), g = Gravity (m/s²)
Planetary Gravity
Earth: 9.81 m/s²
Moon: 1.62 m/s²
Mars: 3.71 m/s²
Jupiter: 24.79 m/s²
Sun: 274 m/s²
Mass vs Weight
Μάζα: Amount of matter (constant)
Βάρος: Force due to gravity (varies)
Your mass is the same everywhere, but your weight changes with gravity.
Σημαντικές Σημειώσεις
- Weight depends on gravity
- Mass is constant regardless of location
- Standard Earth gravity: 9.80665 m/s²
- Weight on Moon is about 1/6 of Earth
- Weight on Jupiter is about 2.5× Earth
- Use Newtons for scientific calculations
