To convert ke to nanoseconds, multiply the value by 900,000,000,000. To go the other way, multiply nanoseconds by 1.11111 × 10⁻¹² to get ke.

Ke (ke). The Chinese ke is a quarter hour (15 minutes) in modern use. Used in: Asia — China (traditional).
Nanosecond (ns). A nanosecond is one billionth of a second — light travels about 30 cm in that time.
There are 900,000,000,000 nanoseconds in one ke.
Multiply the number of ke by 900,000,000,000. For example, 10 ke equal 9,000,000,000,000 nanoseconds.
One nanosecond equals 1.11111 × 10⁻¹² ke.
10,800,000,000,000 nanoseconds. Other common values: 5 ke = 4,500,000,000,000 nanoseconds and 100 ke = 90,000,000,000,000 nanoseconds.
