Elevation Feet to Meters Converter

Elevation feet to metres is an exact length conversion

One international foot equals exactly 0.3048 metres. This makes it straightforward to translate elevation values between aviation, hiking, engineering and international datasets.

The converted number is only as accurate as the original elevation source. GPS, DEM and surveyed heights can differ because of measurement quality and vertical datum.

When this tool is useful

Use Elevation Feet to Meters Converter when the question matches the method the page actually uses. Typical workflows include:

• Use the output as a planning or teaching reference, then move to an official or specialist source if the result affects legal, safety, engineering or financial decisions.
• Run the same workflow for locations in different countries while keeping units and assumptions consistent.
• Answer a one-off question about elevation feet to meters converter and keep the result tied to a visible map or explicit input.

Worked examples

These examples are meant to show how to interpret this kind of output, not to replace the values produced from your own inputs.

• Eye height near sea level — With eyes about 1.7 m above sea level, the refracted-horizon estimate is roughly 5 km.
• 100 m viewpoint — At 100 m elevation above a clear horizon, the estimate increases to roughly 39 km.
• Antipode example — New York's antipodal coordinate is approximately -40.71, 105.99.

How to interpret the result

The most common errors come from using a correct result to answer the wrong geographic question. Keep these points in mind for Elevation Feet to Meters Converter:

• Treat climate and hardiness outputs as 30-year character, not this year's weather: a zone tells you what winters usually allow, and microclimates — walls, slopes, urban heat — shift a real garden half a zone either way.
• Remember that elevation models see bare terrain: no buildings, no forest canopy. A line-of-sight 'clear' verdict can still be blocked by a wood, and a horizon distance assumes open ground — treat results as the terrain baseline, then add land cover from local knowledge.

Limits & appropriate use

Terrain intelligence carries one dominant limit: the model sees bare earth at ~90 m spacing with metres of vertical error, and is blind to canopies, walls and wires. Every downstream answer inherits it — profiles show terrain truth with noisy amplitude, line-of-sight verdicts are pending trees, horizons assume open ground, and solar radiation averages assume an unshaded panel. The second limit is temporal: climate letters and hardiness zones are thirty-year character, not this year's behaviour, and seismicity is a mood, not a hazard model. Each result here is printed with its recipe precisely so these boundaries travel with the number.

The value proposition is screening-grade truth at zero cost: orientation for sites, gardens, antennas, shoots and curiosity, with the upgrade points clearly marked. When money or safety attaches to the answer — tower siting, flood insurance, structural shading, avalanche terrain — the escalation is professional: licensed survey, certified shade studies, regulatory flood determinations and geological hazard services. A good free tool makes that ladder visible instead of pretending to be the top of it.

• Construction and tower siting → licensed topographic survey.
• Flood decisions → regulatory determinations (FEMA/FIRM in the US).
• Solar finance → certified shade and production studies.

Data & methodology

Uses the exact international conversion 1 foot = 0.3048 metres. Elevation and radiation use Open-Meteo's open API on Copernicus/ERA5 datasets; visibility math adds standard refraction (k = 0.13). US hydrology/flood layers come from USGS and FEMA public services.

Key terms worth knowing

DEM

Digital elevation model: a grid of terrain heights, e.g. Copernicus GLO-90.

Refraction coefficient

The standard 0.13 factor bending sightlines over the curvature.
