1 kilonewton is approximately equal to 0.102 tons.

1. On the surface of the earth, 1kN = (1000kg /9.8) X g. 1 kN is approximately equivalent to the gravity of an object of 102 kilograms.

2. Ton, one of the units of mass. 1 ton is 1000 kilograms, specifically the weight of 1 cubic meter of water at 4 degrees Celsius at standard atmospheric pressure. 1,000 kilograms (kg) = 1 ton (t)

3. The kilogram (symbol kg) is the basic unit for measuring mass in the International System of Units. The kilogram is also one of the most commonly used basic units in daily life. The definition of a kilogram is the mass of the International Prototype Kilogram, which is almost the same weight as a liter of water. 1 kilogram = 0.001 metric ton (or "ton").

Extended information:

1. The kilonewton is a commonly used unit in engineering design and mechanical calculations. It is the unit of force, while the kilogram is a unit of mass and cannot be directly converted to mass.

2. Kilogram is the unit of mass, and mass is equivalent to how "heavy" something is in everyday terms. However, mass is actually a property of "inertia"; that is, an object tends to maintain its velocity in the absence of external forces. When an object with a mass of one kilogram is acted upon by a force of one Newton, it will gain an acceleration of one meter per square second.

3. In mechanics, by selecting the three physical units of length, mass and time as the basic units, the units of the remaining physical quantities can be derived. Selecting different units of these three physical quantities can form different mechanical unit systems. In the International System of Units (SI), m (unit of length), kg (unit of mass), and s (unit of time) are taken as the basic units.
