How is the conversion unit of time converted, such as seconds, milliseconds, subtleties, nanoseconds, etc.
Universal time unit conversion:

1 sec = 1000 ms (milliseconds)

1 sec = 1, 000,000 microseconds (microseconds)

1 sec = 1, 000,000,000 nanoseconds (ns)

1 sec = 1, 000,000,000,000,000 picoseconds

1 sec = 1.0 billion femtoseconds

The conversion rate between seconds, milliseconds, microseconds, nanoseconds, picoseconds and femtoseconds is 1000.

Extended data:

Millisecond is a relatively small unit of time, called ms for short. The minimum exposure time of a typical camera is one millisecond. A housefly flaps its wings every three milliseconds; Mosquitoes flap their wings every 20 milliseconds; Bees flap their wings every five milliseconds. Because the moon's orbit around the earth is gradually widening, it takes two milliseconds more for it to make a circle every year.

Microseconds, μs for short. During this time, light can travel 300 meters, which is about the length of three football fields, but the sound wave at sea level can only travel 1/3 mm, and the high-speed commercial stroboscope flashes about 1 microsecond at a time. A barrel of explosives began to explode about 24 microseconds after the fuse blew.

Nanosecond, ns for short. Usually used as a unit of memory reading and writing speed. Light can only travel 30 centimeters (less than one step) in a nanosecond in a vacuum. It takes about 2 to 4 nanoseconds for a microprocessor of a personal computer to execute an instruction, such as adding two numbers. Another rare subatomic particle, the k meson, exists in12ns.

Picosecond, ps for short. The fastest transistor runs in picoseconds. A rare subatomic particle B quark produced by high-energy accelerator can exist 1 picosecond before decay. The average existence time of hydrogen bonds between water molecules at room temperature is 3 picoseconds.

Femtosecond is also called femtosecond, or fs for short. The oscillation period of visible light is 65438 0.30 to 2.57 femtoseconds. It takes 10 to 100 femtoseconds for an atom in a molecule to complete a typical vibration. It usually takes hundreds of femtoseconds to complete a rapid chemical reaction. The interaction between light and pigments on the retina (the process of producing vision) takes about 200 femtoseconds.
