How 60 lb Concrete Bag Calculator Works?
To count 60 lb bags, the 60 lb Concrete Bag Calculator divides the tube volume by 0.45 cubic feet (ft³), the yield of a 60 lb (27 kg) bag. The process takes 4 steps.
Enter tube size and count
Type the diameter, depth and number of forms.
Calculate volume
The tool finds the fill in ft³ with your waste margin.
Divide by 0.45 ft³
One 60 lb bag yields 0.45 ft³ (12.7 L) of concrete.
Compare with 80 lb
The calculator shows how many extra bags the 60 lb size adds compared with 80 lb bags: 4 bags of 60 lb equal 3 bags of 80 lb.
60 lb Concrete Bag Calculator Formula
The 60 lb Concrete Bag Calculator uses a 0.45 ft³ yield.
Bag count
Bags = ⌈V ÷ 0.45⌉V in ft³.
Ratio to 80 lb
B_60 = B_80 × 4 ÷ 3Same concrete, 33% more bags.
Water per bag
≈ 2.25 quarts (2.1 L)Scale label water to bag weight.
Worked example: 6 piers at 10 in × 48 in, 10% waste
- V = 6 × 2.182 × 1.10 = 14.40 ft³
- Bags = ⌈14.40 ÷ 0.45⌉ = 32 bags of 60 lb
- Same job in 80 lb bags = 24 bags
60 lb Concrete Bag Calculator Conversion Table
The 60 lb bag conversion table lists tube height per bag and bags needed at 36 in and 48 in depths.
| Tube | Height per bag | Bags at 36 in | Bags at 48 in | Bags at 48 in + 10% |
|---|---|---|---|---|
| 6 in (15 cm) | 27.5 in | 2 | 2 | 2 |
| 8 in (20 cm) | 15.5 in | 3 | 4 | 4 |
| 10 in (25 cm) | 9.9 in | 4 | 5 | 6 |
| 12 in (30 cm) | 6.9 in | 6 | 7 | 8 |
| 16 in (41 cm) | 3.9 in | 10 | 13 | 14 |
| 18 in (46 cm) | 3.1 in | 12 | 16 | 18 |
One 60 lb bag yields 0.45 ft³ (12.7 L, 0.0127 m³).
What is 60 lb Concrete Bag Calculator?
A 60 lb Concrete Bag Calculator is a bag counter set to the 0.45 ft³ yield of a 60 lb (27 kg) bag of premixed concrete.
The 60 lb bag is the middle size on most store shelves. It is easier to lift than an 80 lb bag and gives 50% more concrete than a 40 lb bag. A 10 in tube rises 9.9 in per bag, so a 48 in deck pier takes 5 bags.
The calculator suits DIY crews of 1 or 2 people who mix in a wheelbarrow, where 60 lb loads are easier to dump and stir.
What are the uses of 60 lb Concrete Bag Calculator?
There are 4 main uses of the 60 lb Concrete Bag Calculator.
DIY deck piers
Owners fill 8 in to 12 in deck tubes with lighter bags.
Wheelbarrow mixing
Crews mix 2 bags of 60 lb per wheelbarrow load.
Mid-size orders
Buyers compare cost per ft³ with 80 lb bags.
Mixed crews
Supervisors pick a bag size every crew member can carry.
