The relationship of 1 kg per hectare to 2.24 times parts per million (ppm) typically refers to the concentration of a substance in a soil or crop context. In agricultural terms, applying 1 kg of a nutrient or chemical per hectare can result in an increase of 2.24 ppm in the soil or plant tissue, depending on the specific nutrient's density and the volume of soil or biomass being considered. This conversion factor helps farmers and agronomists understand the impact of their fertilizer or amendment applications on nutrient levels.

You cannot. Kilogram per hectare is a measure of mass per area whereas part per million is a pure ratio - without units. According to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
1 mg/kg = 1 ppm 1 mg = 1000 micrograms (ug) so 10 ug/kg = 0.01 mg/kg = 0.01 ppm
A kilogram is a unit of mass; a hectare is a unit of area. There is no standard conversion between the two. If you say "kg per ha", presumably you need a certain amount of a certain substance, for example, to spray a hectare. This will vary from one substance to another. The amount, 2.24, only applies to one specific substance, and for one specific purpose.
To convert parts per million (ppm) to grams per kilometer (g/km), you can use the formula: [ \text{g/km} = \text{ppm} \times \frac{\text{mass of the substance}}{\text{mass of the solution}} \times \frac{1 \text{ km}}{1,000,000 \text{ g}} ] Assuming a 1 kg mass of solution (1,000 g), the conversion simplifies to: [ \text{g/km} = \text{ppm} \times 0.001 ] Thus, for every 1 ppm, you have 0.001 g/km.
1 (kg / liters) per second = 3600 (kg / liters) per hour. So, multiply kg/l per second by 3,600 to get kg/l per hour.
