How this is calculated

Formula:

target = source × factor

In plain language:

All inputs normalize to meters; the calculator scales from meters to the requested unit using exact definitions (e.g., 1 ft = 0.3048 m, 1 mi = 1609.344 m, 1 NM = 1852 m).

The formula is always visible so you can verify the math and explain your numbers to anyone who asks.

Distance converter explained

Use this converter to hop between common distance units without memorizing factors. It covers everyday measures like meters, feet, and miles, plus travel-friendly units such as kilometers and nautical miles.

How the conversion works

All units share the meter as a base. Convert any input to meters, then scale to the target unit:

\text{meters} = \text{input} \times \text{to\_meter\_factor}

\text{target} = \frac{\text{meters}}{\text{from\_meter\_factor}}

Units and conversions

Unit	Symbol	Relation to 1 meter
Meter	m	1
Kilometer	km	1 km = 1,000 m
Mile	mi	1 mi = 1,609.344 m
Yard	yd	1 yd = 0.9144 m
Foot	ft	1 ft = 0.3048 m
Inch	in	1 in = 0.0254 m
Nautical mile	NM	1 NM = 1,852 m

Worked examples

Trail length in kilometers Given 12 mi:
$\text{meters} = 12 \times 1{,}609.344 = 19{,}312.128\,\text{m}$ $\text{km} = \frac{19{,}312.128}{1{,}000} = 19.312\,\text{km}$
Result: 19.312 km.
Converting site distance for a layout plan Given 2{,}500 m:
$\text{feet} = \frac{2{,}500}{0.3048} = 8{,}202.10\,\text{ft}$ $\text{yards} = \frac{2{,}500}{0.9144} = 2{,}734.03\,\text{yd}$
Result: 8,202.10 ft or 2,734.03 yd.

Tips and pitfalls

Keep 3–4 significant figures for engineering drawings; round to 1–2 for travel distances.
Nautical miles are defined from the Earth ellipsoid; use NM for aviation and maritime planning, not for road trips.
If precision matters, avoid chaining conversions (mi → ft → m); go through meters once to reduce rounding drift.
