What is a Kilogram (kg)?

kilogram (kg) is the SI base unit of mass. It measures the amount of matter in an object, not the force.

Key Facts About Kilograms

  • Base unit of mass in SI.
  • 1 kg = 1000 grams.
  • Abbreviation: kg.
  • Usage: Weight measurement, science, and daily use.

What is a Newton (N)?

newton (N) is the SI unit of force. It represents the force required to accelerate 1 kg of mass by 1 m/s².

Key Facts About Newtons

  • Exact value: 1 N = 0.10197 kgf.
  • Relationship: 1 N = 1 kg·m/s².
  • Abbreviation: N.
  • Usage: Physics, mechanics, engineering, and weight under gravity.

    Step 3: Result = 1.02 kg
     
  • 50 N to kg
    Step 1: kg = N ÷ 9.80665
    Step 2: Substitute = 50 ÷ 9.80665
    Step 3: Result = 5.10 kg
     
  • 100 N to kg
    Step 1: kg = N ÷ 9.80665
    Step 2: Substitute = 100 ÷ 9.80665
    Step 3: Result = 10.20 kg
