Souped-up sounding rocket lifts off from Japan with tiny satellite
A modified sounding rocket originally designed to loft science instruments on high-altitude suborbital arcs blasted off Saturday from the Uchinoura Space Center in southern Japan and soared into orbit to become the world's smallest satellite launcher.
[...] Standing just 31 feet (9.5 meters) tall and spanning around 20 inches (52 centimeters) in diameter, the SS-520-5 rocket was modest by launcher standards. With Saturday's successful flight, the solid-fueled booster became the smallest rocket to ever put an object in orbit around Earth.
A student-built shoebox-sized CubeSat named TRICOM 1R — weighing in at about 10 pounds (3 kilograms) — was mounted on top of the SS-520-5 rocket for liftoff from the Uchinoura Space Center in Japan's Kagoshima prefecture.
[...] The SS-520 is designed to propel more than 300 pounds (140 kilograms) of science research instrumentation to an altitude of nearly 500 miles (800 kilometers) for a few minutes of exposure to space before falling back to Earth. Engineers added a third stage on top of the basic SS-520 booster to give it the capability to reach orbital speeds of more than 17,000 mph (27,000 kilometers per hour).

That conversion makes sense if the reporter (or whoever made the conversion) used a well-versed conversion system, a libra (lb) (the original pound) is about 329g which would make it (3 / 0.329) ~ 9.11 pound, and then add some agressive rounding away from zero...
