100 Knots (kt) = 185.2 km/h
Formula
Ref- Linear: value × (from factor ÷ to factor)
- Temperature is affine: °F = °C × 9/5 + 32, K = °C + 273.15
Worked example
RefConvert 100 knots to km/h.
- 1.1 kt = 1.852 km/h (ICAO nautical mile = 1,852 m).
- 2.100 × 1.852 = 185.2.
100 kt = 185.2 km/h.
How it works
RefAviation lives across unit systems: knots and nautical miles for navigation, feet for altitude, hectopascals or inches of mercury for pressure, litres or gallons for fuel. This converter covers the quantities a pilot switches between daily, including the affine temperature scales.
DGCA student tip
ExamAnchor the essentials: 1 nm = 1.852 km, 1 inch Hg = 33.86 hPa, 1 US gal = 3.785 L, and standard pressure = 1013.25 hPa = 29.92 inHg. Most exam conversions build on these four.
Common mistakes
Watch- Converting nautical to statute miles as if they were equal.
- Treating temperature as a simple ratio instead of an offset scale.
- Mixing US and Imperial gallons — they differ by ~20%.
