The conversion from meters (SI metric unit) to feet (imperial/US customary unit) uses a fixed, internationally standardized relationship.
Exact baseline: \(1\ \text{ft} = 0.3048\ \text{m}\) (exact).
Therefore, \(1\ \text{m} = \dfrac{1}{0.3048}\ \text{ft} \approx 3.28084\ \text{ft}\).
Step-by-step method (meters to feet)
- Start with the length in meters, \(L_{\text{m}}\).
- Multiply by \(3.28084\ \dfrac{\text{ft}}{\text{m}}\) so meters cancel and feet remain.
- Round to the precision required (construction often rounds to 2 decimals; engineering may keep more).
The conversion formula is:
\[ L_{\text{ft}} = L_{\text{m}} \times 3.28084 \]Worked calculation: \(1.2\ \text{m}\) to feet
Substitute \(L_{\text{m}} = 1.2\):
\[ L_{\text{ft}} = 1.2 \times 3.28084 = 3.937008\ \text{ft} \]Rounded to five decimal places: \(3.93701\ \text{ft}\). Rounded to two decimal places: \(3.94\ \text{ft}\).
Quick reference table (near 1.2 m)
| Length (m) | Length (ft) | Rounded (2 d.p.) |
|---|---|---|
| 1.0 | \(1.0 \times 3.28084 = 3.28084\) | 3.28 |
| 1.1 | \(1.1 \times 3.28084 = 3.608924\) | 3.61 |
| 1.2 | \(1.2 \times 3.28084 = 3.937008\) | 3.94 |
| 1.3 | \(1.3 \times 3.28084 = 4.265092\) | 4.27 |
| 1.5 | \(1.5 \times 3.28084 = 4.92126\) | 4.92 |

Common checks
- Magnitude check: feet should be larger numerically than meters because \(1\ \text{m} \approx 3.28\ \text{ft}\).
- Reverse check: multiplying \(3.937008\ \text{ft}\) by \(0.3048\ \dfrac{\text{m}}{\text{ft}}\) returns approximately \(1.2\ \text{m}\).
