# Cubic Feet to Cubic Yards Calculator

> Enter a volume in cubic feet (or another unit) and see it in cubic yards, cubic feet and cubic meters. Handy for bagged mulch, soil and concrete.

**Quick answer:** To convert cubic feet to cubic yards, divide by 27, because a cubic yard is 3 ft × 3 ft × 3 ft. For example, 54 cubic feet is 2 cubic yards and 100 cubic feet is 3.70 cubic yards. One cubic meter equals about 1.308 cubic yards.

## Cubic feet to cubic yards: divide by 27

A cubic yard is a cube that is 3 feet long, 3 feet wide and 3 feet high. That is 3 × 3 × 3 = **27 cubic feet**, so the conversion is one division.

```
cubic yards = cubic feet ÷ 27
cubic feet = cubic yards × 27
```

Example: 100 cubic feet ÷ 27 = **3.70 cubic yards**. Going back, 2.5 cubic yards × 27 = 67.5 cubic feet.

### Bags to cubic yards

Mulch, soil and gravel bags are labeled in cubic feet, usually 1, 2 or 3. To find how many bags make a cubic yard, divide 27 by the bag size: 27 ÷ 2 = 13.5, so about **14 two-cubic-foot bags** per yard. For 1.5 cubic feet it is 18 bags and for 3 cubic feet it is 9.

### A quick way to estimate in your head

Dividing by 27 is awkward, so many people divide by 30 and then add about 10%. For 100 cubic feet: 100 ÷ 30 = 3.33, and 3.33 plus a tenth is 3.67, which is close to the exact 3.70. Use the calculator when the order matters.

### Reading product labels

- **Bagged mulch, soil and sand** are labeled in cubic feet. Multiply the bag size by the number of bags, then divide by 27 to compare with a bulk price per yard.
- **Bulk deliveries** are quoted in cubic yards, sometimes in tons for stone and sand.
- **Readymix concrete** is quoted in yards, while premix bags state their yield in cubic feet on the bag.

### Mistakes to avoid

- Dividing cubic feet by 3 instead of 27. A yard is 3 feet in each of three directions, so the volume factor is 27.
- Dividing square feet by 27. Volume needs a depth first: area × depth in feet.
- Mixing inches and feet. Convert inches to feet by dividing by 12 before multiplying.
- Forgetting that bags hold less than they appear to once poured and spread: check the stated coverage.

If you start from length, width and depth instead, use the [cubic yard calculator](../cubic-yard-calculator/). For specific materials, the [mulch](../mulch-calculator/), [topsoil](../topsoil-calculator/) and [concrete](../concrete-calculator/) calculators work out both yards and bags.
