| 50 g/m² | 500 kg/ha | New lawn establishment / fertiliser |
| 100 g/m² | 1,000 kg/ha | Heavy topdressing or bulk fertiliser |
| 200 g/m² | 2,000 kg/ha | Agricultural crop seeding (e.g., wheat) |

Area Density Conversion FAQ
Everything you need to know about converting g/m² to kg/ha and applying rates correctly.
To convert grams per square metre (g/m²) to kilograms per hectare (kg/ha), simply multiply the g/m² value by 10. For example, 50 g/m² multiplied by 10 equals 500 kg/ha.
The formula is: kg/ha = g/m² × 10. This works because 1 hectare equals 10,000 square metres, and 1 kilogram equals 1,000 grams. Therefore, (g/m² × 10,000 m²/ha) ÷ 1,000 g/kg simplifies to g/m² × 10.
This conversion is essential in agriculture, landscaping, and turf management. Small-scale trials, garden packets, or scientific studies often specify rates in g/m², while large-scale farm machinery and commercial fertiliser applications are calibrated in kg/ha. This tool bridges that measurement gap.
100 grams per square metre is exactly equal to 1,000 kilograms per hectare (100 × 10 = 1,000). This is a common application rate for certain heavy seeding, bulk fertiliser, or soil topdressing operations.
