Grams per Square Meter to Tonnes per Hectare (g/m2 to t/ha)
1 gram per square meter (g/m²) = 0.01 tonnes per hectare (t/ha). 1 t/ha = 100 g/m². Example: 15 g/m² = 15 × 0.01 = 0.15 t/ha.

How to Convert Gram per Square Meter to Tonne per Hectare
- 1 g/m² = 0.01 t/ha
- 1 t/ha = 100 g/m²
- Example: convert 15 g/m² to t/ha: 15 g/m² = 15 × 0.01 t/ha = 0.15 t/ha
Formula
t/ha = g/m² ÷ 100
Derivation from SI units:
- 1 g/m² = 10 kg/ha.
- 1 t/ha = 1000 kg/ha.
- 1 g/m² = 10 kg/ha ÷ 1000 kg/ha per t/ha = 0.01 t/ha
Both units are defined exactly, so the factor is exact. Gram per Square Meter definition: gram per square meter; Tonne per Hectare definition: tonne per hectare.
Worked examples
- A reading of 10 g/m² converts to 0.1 t/ha.
10 g/m² × 0.01 = 0.1 t/ha - A value of 25 g/m² is 0.25 t/ha.
25 g/m² × 0.01 = 0.25 t/ha

Frequently asked questions
How many tonnes per hectare are in 1 gram per square meter?
1 g/m² = 0.01 t/ha.
How do I convert grams per square meter to tonnes per hectare?
Multiply the value in g/m² by 0.01, or divide it by 100. For example, 15 g/m² × 0.01 = 0.15 t/ha.
Is the g/m² to t/ha conversion exact?
Yes. Both units are defined exactly, and 1 g/m² is exactly 0.01 t/ha.
