Issues you may run into
| What you see | Why it happens | What to do |
|---|---|---|
| The answer is far too big or too small | The linear factor (0.3048) was used instead of the squared one. | Use 0.09290304 for areas. |
| Cubic or linear measures | This is for area only. | Use the length or volume converters for other quantities. |
| Carpet or tile area differs | Net and gross areas differ. | Add waste on top of the converted area. |
Assumptions and limitations
