RVR to Visibility Conversion Chart
The 14 CFR 91.175(h) table that equates RVR with ground visibility, alongside exact distance conversions between feet, metres, statute miles and nautical miles. The two are not the same thing, so the chart shows both.
Standards and method
The RVR-to-visibility equivalences are quoted from 14 CFR 91.175(h)(2); every other value is an exact distance conversion.

Full RVR and visibility conversion chart
Runway visual range in feet and metres, the 14 CFR 91.175 RVR-to-visibility table, and statute miles to metres. These are the same tables as the printable PDF. For: Pilots, flight students, dispatchers and flight instructors.
- Key relationship
- 1 ft = 0.3048 m; 1 statute mile = 5,280 ft = 1,609.344 m (exact)
- Formula
- metres = feet × 0.3048; statute miles = feet ÷ 5,280
- Reverse
- feet = metres ÷ 0.3048
- Worked example
- RVR 2,400 ft = 731.5 m; the 91.175(h) table equates it to 1/2 SM visibility
- Rounding
- Metres to the nearest metre, miles to 2 decimals. The regulatory table is not a unit conversion: use it only as 91.175(h) allows.

RVR and visibility: what to know
| Point | Detail |
|---|---|
| RVR | Runway visual range: how far a pilot on the runway centreline can see the runway lights or markings, measured by instruments. |
| Ground visibility | Prevailing visibility reported by an observer or automated system (statute miles in the US, metres elsewhere). |
| 91.175(h) | Applies only when RVR is not reported for the runway of intended operation, and not to Category II or III minimums. |
| Not a conversion | RVR 1,600 ft is 0.30 SM as a distance, but the rule equates it to 1/4 SM: use the table, not arithmetic. |

RVR to Visibility Conversion Chart FAQs
Common questions about the RVR and visibility conversion chart.
What is RVR 2,400 in statute miles?
Under 14 CFR 91.175(h)(2), when RVR is not reported an RVR minimum of 2,400 ft is converted to 1/2 SM ground visibility. As a straight distance, 2,400 ft is 0.45 SM (732 m).
What is an RVR of 1,400 in SM?
The 91.175(h) table starts at RVR 1,600 ft = 1/4 SM, so it gives no visibility equivalent for 1,400. As a distance, 1,400 ft is 427 m or 0.27 SM.
What is the difference between RVR and visibility?
RVR is measured by instruments along the runway and says how far a pilot can see the runway lights or markings. Visibility is the prevailing visibility reported for the airport.
