Tonnes per Hectare to Grams per Square Meter (t/ha to g/m2)
1 tonne per hectare (t/ha) = 100 grams per square meter (g/m²). 1 g/m² = 0.01 t/ha. Example: 15 t/ha = 15 × 100 = 1500 g/m².

How to Convert Tonne per Hectare to Gram per Square Meter
- 1 t/ha = 100 g/m²
- 1 g/m² = 0.01 t/ha
- Example: convert 15 t/ha to g/m²: 15 t/ha = 15 × 100 g/m² = 1500 g/m²
Formula
g/m² = t/ha × 100
Derivation from SI units:
- 1 t/ha = 1000 kg/ha.
- 1 g/m² = 10 kg/ha.
- 1 t/ha = 1000 kg/ha ÷ 10 kg/ha per g/m² = 100 g/m²
Both units are defined exactly, so the factor is exact. Tonne per Hectare definition: tonne per hectare; Gram per Square Meter definition: gram per square meter.
Worked examples
- A reading of 4 t/ha converts to 400 g/m².
4 t/ha × 100 = 400 g/m² - A value of 10 t/ha is 1000 g/m².
10 t/ha × 100 = 1000 g/m²

Frequently asked questions
How many grams per square meter are in 1 tonne per hectare?
1 t/ha = 100 g/m².
How do I convert tonnes per hectare to grams per square meter?
Multiply the value in t/ha by 100. For example, 15 t/ha × 100 = 1500 g/m².
Is the t/ha to g/m² conversion exact?
Yes. Both units are defined exactly, and 1 t/ha is exactly 100 g/m².
