15 meters (150 decimeter, 1500 cm, etc ...)
590 inches
49 feet
16 yards
0.0093 miles
0.008 nautical miles
3 rods
0.075 furlongs
1800 barleycorns
147.63 hands
66 spans
33 cubits
13 ells
8.2 fathoms
75 links
0.75 chains
0.0027 leauges
0.03 li
0.081 stadia
4.8e-16 parsecs
1e-10 astronomical units
5e-8 lightseconds
2.8e11 Bohr radiuses
9.2e35 Plank lenghts

and probably most appropriately (being dutch):

1.5 roede

In other words "a stone's throw away".
