To convert to kilograms: multiply by 9.80665.
1 kgf·s²/m = 9.80665 kg (exactly), based on standard gravity g₀ = 9.80665 m/s².
For example, 1 Kilogram-force second²/meter (kgf·s²/m) = 9.806650e-15 Exagram (Eg).

The kilogram-force second squared per meter is an engineering unit of mass in the gravitational metric system, equal to about 9.807 kg.
1 kgf·s²/m = 9.80665 kg (exactly), based on standard gravity g₀ = 9.80665 m/s².
To convert to kilograms: multiply by 9.80665.
Historical engineering calculations where force was in kgf and F=ma needed consistent units.
This unit is the metric equivalent of the slug (imperial system). Just as 1 lb-force accelerates 1 slug at 1 ft/s², 1 kgf accelerates this unit at 1 m/s².
Mixing up mass (kg) and weight (kgf) in the gravitational system. SI removed this confusion by using newtons for force.
This unit exists because the gravitational system used kgf (force) as base, so a derived mass unit was needed for F=ma to work.
The exagram equals 10¹⁸ grams or 10¹⁵ kilograms — one trillion tonnes.
1 Eg = 10¹⁸ g = 10¹⁵ kg = 10⁹ tonnes.
To convert Eg to kg: multiply by 10¹⁵. To convert Eg to Pg: multiply by 1,000.
No everyday applications. Describes masses of small moons or large asteroids.
Earth's total mass is about 5.97 × 10⁶ Eg. The entire atmosphere weighs 'only' about 5 Eg.
Hardly ever encountered — most contexts use 'times 10^x kg' notation instead of exagrams.
If you need to express masses between Pg and Earth-masses, the exagram fills that gap: 1 Eg = 10¹⁵ kg.
