1 million × 4000 = 1000000 × 4000 = 4000000000 = 4 x 10^9 * In those countries which use the long scale (based on powers of a million) eg Europe: 4 × 10^9 = 4000 x 10^6 = 4 thousand million or 4 milliard * In those countries which use the short scale (based on powers of a thousand plus one) eg USA: 4 x 10^9 = 4 billion.
