The math: cubic yards × 27 = cubic feet, then divide by the bag's yield (0.60, 0.45, 0.375 or 0.30 ft³) and round up. Add your waste allowance before you divide, or enter it in the converter above.

Metric bags per cubic meter

Using 0.008 m³ per 20 kg and 0.010 m³ per 25 kg (Hanson)
Cubic meters	20 kg	25 kg
0.25 m³	32	25
0.5 m³	63	50
1 m³	125	100
2 m³	250	200

Metric bag yields vary more between brands than US ones; one Australian 20-kg mix lists 0.010 m³ and one New Zealand 25-kg mix lists 0.012 m³. Check the bag and see the methodology.

Is a yard of bags worth it?

45 bags of 80 lb is 3,600 lb to load, haul, mix and place. Plan on a mixer and helpers. Read ready-mix vs bags before you buy a pallet.
