🔄 Quick Convert Meganewton
What is a Meganewton?
The meganewton (MN) is a metric unit of force equal to 1,000,000 newtons or 1,000 kilonewtons. Used for very large forces in heavy engineering, aerospace propulsion, large-scale construction, and naval architecture applications.
History of the Meganewton
Derived from the SI unit newton with the SI prefix mega- (10⁶). Became common in heavy engineering and aerospace applications as equipment and structures grew larger in the mid-20th century. Standard unit for rocket thrust and mega-structure loads.
Quick Answer
What is a Meganewton? A meganewton (MN) is a metric unit of force equal to 1,000,000 newtons (1 million N) or 1,000 kilonewtons. It measures extremely large forces: 1 MN ≈ weight of 102 metric tons, 10 MN ≈ large rocket engine thrust, 100 MN ≈ skyscraper foundation load. Used in aerospace propulsion, mega-structures, ship propulsion, and heavy industrial applications. Use our force converter to convert meganewtons to newtons, kilonewtons, and other units instantly.

Definition
The meganewton (MN) equals 1,000,000 newtons. It measures very large forces in SI units.
Formula: 1 MN = 1,000,000 N = 10⁶ kg⋅m/s²
Conversions:
- 1 MN = 1,000,000 N (newtons)
- 1 MN = 1,000 kN (kilonewtons)
- 1 MN = 224,809 lbf (pounds-force)
- 1 MN = 101,972 kgf (kilogram-force)
- 1 MN = 224.809 kip
- 1 MN = 10¹² dynes
History
The meganewton emerged as engineering projects scaled up dramatically in the mid-20th century. When the newton was adopted in 1948, engineers working on rockets, large bridges, skyscrapers, and heavy industrial equipment needed a convenient unit for forces exceeding millions of newtons. The meganewton became standard in aerospace engineering with the space race of the 1960s, when rocket thrust ratings commonly exceeded 1 MN. Today, MN is the preferred unit for very large structural loads, ship propulsion systems, industrial presses, and launch vehicle thrust specifications.
