NM-per-Minute Pace Calculator
The professional's mental gear: convert any speed to nautical miles per minute and back, with the timing anchors that make cockpit math instant.
The 6-minute trick is the crown jewel: distance covered in 6 minutes is ground speed with the zero knocked off. 150 kt → 15 nm per 6 minutes. Two GPS distance readings 6 minutes apart hand you your GS with no arithmetic at all.

About NM-per-Minute Pace Calculator
Professional pilots don't divide by sixty in their heads — they think in nautical miles per minute and let the arithmetic collapse: 2 nm/min at 120 knots, 2.5 at 150, a 23-mile leg at 2.5 is nine-something minutes, done. This calculator builds that fluency: any speed to pace, any leg timed at it, and the 6- and 10-minute checkpoint distances that turn dead reckoning into pattern recognition.

Frequently asked questions
What is the 6-minute trick exactly?+
Six minutes is a tenth of an hour, so distance covered in 6 minutes equals ground speed divided by ten — drop the zero: 150 kt covers 15 nm. Inverted, it measures GS without dividing: note GPS distance-to-waypoint, wait six timed minutes, note again; the difference × 10 is your ground speed. Approach controllers, instructors and ferry pilots all run on it.
Which paces are worth memorizing cold?+
Your three operating speeds: climb GS, cruise GS and approach GS as nm/min (say 1.3 / 2.0 / 1.5). With those anchored, every cockpit question — minutes to the FAF, descent start, fuel at the alternate — becomes one multiplication of a small number. Jet crews think 7–8 nm/min the same way; the gear scales.
How does pace thinking help on instrument approaches?+
Procedure timing tables are pace tables: an outbound leg of 2 minutes at 90 kt is 3 nm; a 5-DME arc at 1.5 nm/min forecasts the lead radial's arrival. When GPS distance and your pace disagree noticeably, something — wind, speed discipline, the wrong waypoint — has changed, and pace fluency is what makes you notice in seconds.
Is there a metric equivalent for km/h pilots?+
Divide km/h by 60 for km/min: 180 km/h = 3 km/min. The 6-minute trick still works (km in 6 min = km/h ÷ 10). Ultralight and glider pilots in metric airspace use it identically — pace arithmetic is unit-agnostic; only the anchors change.
