1 Short scale usage

In short scale usage, a quadrillion is equal to a 1 with 15 zeroes, namely: 1,000,000,000,000,000 ( 10¹⁵)

It is a thousand million million. The SI prefix for this number is peta.

2 Long scale usage

In long scale usage, a quadrillion is equal to a 1 with 24 zeroes, namely: 1,000,000,000,000,000,000,000,000 ( 10²⁴)

It is a million million million million. The SI prefix for this number is yotta.

While people in the British Isles, Australia and New Zealand traditionally employed the long scale usage, they have largely switched to the short scale usage.
