Cubic Feet to Cubic Yards Calculator

This calculator converts a volume in cubic feet into cubic yards, the unit bulk soil, mulch and gravel are sold in. Enter the cubic feet; you get cubic yards, cubic metres and litres.

Formula

Cubic yards = cubic feet ÷ 27, because a cubic yard is 3 ft × 3 ft × 3 ft = 27 ft³. Cubic metres = cubic feet × 0.028316846592 (exact). Litres = m³ × 1,000.

• v: volume in cubic feet

Worked Example

54 ft³ of mulch.

1. Cubic yards = 54 ÷ 27 = 2.000 yd³
2. Cubic metres = 54 × 0.0283168 = 1.529 m³
3. Litres = 1.529 × 1,000 = 1,529 L

How to use the result

Bagged products are labelled in cubic feet (often 2 or 3 ft³ for mulch, 0.75 or 1 ft³ for soil), while bulk yards sell by the cubic yard. Divide by 27 to compare a pile of bags with a bulk delivery.

Cubic feet to cubic yards table

Cubic feet	Cubic yards	Cubic metres	Bags of 2 ft³ (rounded up)
1 ft³	0.037 yd³	0.028 m³	1 bags of 2 ft³
2 ft³	0.074 yd³	0.057 m³	1 bags of 2 ft³
3 ft³	0.111 yd³	0.085 m³	2 bags of 2 ft³
5 ft³	0.185 yd³	0.142 m³	3 bags of 2 ft³
10 ft³	0.370 yd³	0.283 m³	5 bags of 2 ft³
13.5 ft³	0.500 yd³	0.382 m³	7 bags of 2 ft³
20 ft³	0.741 yd³	0.566 m³	10 bags of 2 ft³
27 ft³	1.000 yd³	0.765 m³	14 bags of 2 ft³
40 ft³	1.481 yd³	1.133 m³	20 bags of 2 ft³
54 ft³	2.000 yd³	1.529 m³	27 bags of 2 ft³
81 ft³	3.000 yd³	2.294 m³	41 bags of 2 ft³
100 ft³	3.704 yd³	2.832 m³	50 bags of 2 ft³
135 ft³	5.000 yd³	3.823 m³	68 bags of 2 ft³
270 ft³	10.000 yd³	7.646 m³	135 bags of 2 ft³

13.5 bags of 2 ft³ fill one cubic yard, so a 1 yd³ bulk load replaces 14 bags.

Limits and common mistakes

• Divide by 27, not 9: 9 converts square feet to square yards.
• Bulk materials settle, so a delivered yard can fill less once spread and compacted.

Frequently Asked Questions

How many cubic feet are in a cubic yard?

27 ft³.

How many 2 cubic foot bags make a yard?
