From

Beaufort Scale

Bft

The Beaufort scale is an empirical wind-force scale from 0 (calm) to 12 (hurricane). Created by Francis Beaufort in 1805, it correlates wind force with observed effects on sea or land. Force 8 (34–40 knots) is a gale; force 12 is above 64 knots.

Real-world: Force 5 (fresh breeze): 17–21 knots, white-caps form. Force 8 (gale): 34–40 knots. Force 12: 64+ knots.

Kilometer per Hour

km/h

Kilometres per hour (km/h) is the standard speed unit in most of the world. European motorways typically allow 120–130 km/h; urban limits are 50 km/h. Car speedometers in metric countries are marked in km/h, often with smaller mph numbers for US and UK travel.

Real-world: German Autobahn typical speed: 130 km/h (recommended) to 180+ (no limit sections). French limit: 130 km/h. Urban: 50 km/h.

Tips & common mistakes

Quick tips

Beaufort is empirical — conversion to m/s uses v = 0.836 × B^1.5.
Force 4 (moderate breeze) = 5.5–7.9 m/s.
Marine forecasts still use Beaufort alongside knots.

Avoid these

Treating Beaufort as a linear scale — it is a power relationship.
Converting Beaufort to km/h by multiplying — always use the empirical formula.
Using Beaufort for land winds — it was designed for sea conditions.

Frequently asked questions

How many kilometers per hour in a beaufort scale?

One beaufort scale equals 3.6 kilometers per hour.

How do I convert Beaufort to kilometers per hour?

Multiply the beaufort scale value by 3.6 to get the equivalent in kilometers per hour.

What is 100 Beaufort in kilometers per hour?

100 Beaufort equals 360 kilometers per hour.

Is a beaufort scale bigger than a kilometer per hour?

Yes. 1 beaufort scale equals 3.6 kilometers per hour, so one beaufort scale is larger.

How to convert Beaufort to kilometers per hour without a calculator?

Multiply by 3.6 for a quick estimate; use a calculator for precise results.
