1 Mile Pace Calculator

The 1 Mile is 1.61 km (1 miles · 1609 m). At an even 5:00 /km (8:03 /mile) it takes 8:03 — that is 12 km/h (7.45 mph). Enter your own target time below.

Pace and speed are derived from one exact figure — your speed in metres per second — so min/km, min/mile, km/h and mph all agree and round-trip exactly. 1 mile = 1609.344 m.

Note: The mile is exactly 1609.344 m, so a 4:00 mile is exactly 15.0 mph and a 6:26/mile equals 4:00/km.

1 Mile race-time predictions (Riegel estimate)

If your 1 Mile is worth 8:03, the Riegel formula estimates these equivalent times at other distances. These are estimates — real results depend on training, terrain and pacing.

How 1 Mile pace is calculated

Pace is simply time ÷ distance. This page works it out exactly: it converts your 1 Mile into metres and your time into seconds, divides to get one speed in metres per second, then expresses that single number as min/km, min/mile, km/h and mph. Because a kilometre is exactly 1000 m and a mile exactly 1609.344 m, the four figures always agree and convert back to machine precision. Only the Riegel predictions above are estimates.

FAQ

What is a good 1 Mile time?

"Good" depends entirely on the runner, but a useful reference point is even pacing. At 5:00 /km (8:03 /mile) a 1 Mile takes 8:03. Enter your own target above and the calculator shows the exact pace and speed you need; the pace chart below lists finish times for every pace from 3:00 to 8:00 /km.

How many kilometres is a 1 Mile?

A 1 Mile is 1.61 km, which is 1 miles (1609 m). A mile is exactly 1609.344 m, so the conversion is exact rather than rounded.

What pace do I need for a 8:03 1 Mile?

To finish a 1 Mile in 8:03 you hold 5:00 per kilometre, which is 8:03 per mile, or 12 km/h (7.45 mph). The split table below shows the clock at every kilometre and mile for that pace.

How are the 1 Mile race-time predictions calculated?

They use the Riegel formula, t₂ = t₁ × (d₂ / d₁)^1.06, a published 1977 model that scales a known result to another distance. It is an estimate, not a guarantee — real times depend on training, terrain, heat and pacing — and it is the only estimate on this page. Every pace and speed conversion here is exact.
