Regarding time conversion, what is the common time unit conversion?

Think of it this way: 10 minutes passed from 14:50 to 15:00, another hour passed from 15:00 to 16:00 (that is, 60 minutes), plus 30 minutes from 16:30 to 16:30, a total of 100 minutes. This is equivalent to 1 hour and 40 minutes.

It took 1 hour and 40 minutes, or 100 minutes.

It can be calculated like this: from 14:50 to 15:50, it is 1 hour; Add another 10 minutes and it's 16 o'clock; Add another 30 points to 16:30; Together, it's all right.

It took 1 hour and 40 minutes to drive.

14:50 - 15:50 1 hour.

15:50 - 16:10 minutes.

4 p.m. – 4:30 p.m. 30 minutes.

1 + (10 + 30) = 1 hour and 40 minutes.

14:50=2:50=60+60+50=170 minutes.

16:30=4:30=60+60+60+60+30=270 minutes.

So 270-170 = 100 minutes.

It took 100 minutes

1 hour and 40 minutes.

Subtract 14:50 from 16:30 to get it.

Count from 14:50 to 15:00 first

Count from 15:00 to 16:00

Finally, count from 16:00 to 16:30

1 second = 1000 milliseconds (ms).

1 second = 1,000,000 microseconds(s).

1 second = 1,000,000,000 Nanoseconds (ns) 1 second = 1,000,000,000,000,000 Picoseconds (ps) 1 second = 1,000,000,000,000,000 femtoseconds (fs) seconds, milliseconds, microseconds, nanoseconds, picoseconds, femtoseconds, and each of these two stages is converted to 1000.

4. Calculate the time interval across days.

If you subtract this time, you will have a negative number, if it is within 24 hours, you can use this formula: =mod(end time - start time, 1).

As you know, this is generally used to calculate the train usage time, which is perfect for people who are in a hurry.

5. The interval is rounded up to the hour.

Less than an hour is rounded, but it's not rounded, and when I think of overtime hours are counted like this, I can't help but want to cry!

You can use this formula directly: =text(b2-b1,"[h]")<>

Because from 11:36 on October 30, to 11:36, and then to 11:36 on November 01, 48 hours passed, and 11:

01 to 11:36 is 35 minutes, 48 hours - 35 minutes = 47 hours 25 minutes, so, from 11:36 on October 30 to 11:36 on November 01

01 47 hours and 25 minutes passed.

If you are not familiar with the method of calculating time, you can add it like this, for example: Morning Minute to 8:32 Morning.

1. Calculate that the time from morning to morning is 24 hours.

24:00-11:36 = 23:60-11:36 = 12:24 3, calculate the time from zero to 8:32 in the morning.

08:32-00:00=8:32.

24 hours + 12:24 minutes + 8:32 hours = 44 hours 56 minutes.

t=s/v

Time is the seven fundamental physical quantities in physics (length m, time s, mass kg, thermodynamic temperature (Kelvin temperature) k, current unit a, light intensity unit cd (candela)).

Twenty-four hours a day.

Sixty minutes per hour.

Sixty seconds per minute.

This can be calculated for the whole day, and then added up.

The minutes and seconds of time are 60 decimal system, and the algorithm is similar to the decimal system.

The calculation of time is based on the actual calendar, time = due date time - start date time, 24 hours per day.

The morning is 11:36 a.m. on October 30, and the morning is from 0:00:1 a.m. to 12 noon on November 1.

From 10:30 a.m. on October 30 to 10:30 a.m. on November 1, it is two days, or 48 hours.

It can be calculated by the hour or by the approximate number of days.

The unit of time is converted as:

Seconds = 1000 milliseconds (ms).

Milliseconds = 1 1,000 seconds (s) 1 second = 1,000,000 microseconds (us) 1 microsecond = 1 1,000,000 seconds (s).

Seconds = 1,000,000,000 nanoseconds (ns) 1 nanosecond = 1 1,000,000,000 seconds (s).

seconds = 1,000,000,000,000 picoseconds (ps).

Picosecond = 1 1,000,000,000,000 seconds(s).

Expand your knowledge:

The unit of time also has:

Milliseconds (ms), microseconds (us), nanoseconds (ns), picoseconds (ps), femtoseconds (fs), attoseconds, and milliseconds.

Conversion between units:

1s = 10 3ms = 10us = 109ns = 1012ps = 101 fs = 1018 attoseconds = 10 21 seconds = 1043 Planck constant.

Introduction of the units:

1. Milliseconds. A millisecond is a relatively tiny unit of time, one thousandth of a second. The shortest** time for a typical camera is one millisecond.

A housefly flappes its wings every three milliseconds; Mosquitoes flap their wings every 20 milliseconds, bees fan every 5 milliseconds, and the time it takes to make one circle is two milliseconds longer per year as the moon's orbit around the Earth gradually widens.

In computer science, an interval of 10 milliseconds is called a jiffy

2. Microseconds. That's one millionth of a second.

Light can travel 300 meters in this time, which is about the length of 3 football fields in Shengju, but sound waves at sea level can only travel 1 3 mm. High-speed commercial stroboscopes flash once for about 1 microsecond. A simple explosive begins approximately 24 microseconds after its fuse burns out**.

3. Nanoseconds. That is, one billionth of a second, which is equal to 10 to the minus 9th power of seconds (1ns = 10-9s).

Light travels only meters in a nanosecond in a vacuum. It takes about 2 to 4 nanoseconds for a PC's microprocessor to execute a grip command (e.g., adding two numbers together). A rare subatomic particle, the k-meson, exists for 12 nanoseconds.

1 second = 1000 milliseconds (ms).

1 millisecond = 1 1,000 seconds(s).

1 second = 1,000,000 microseconds(s).

1 microsecond = 1 1,000,000 seconds(s).

1 second = 1,000,000,000 nanoseconds (ns) 1 nanosecond = 1 1,000,000,000 seconds (s) 1 second = 1,000,000,000,000 picoacre seconds (ps) 1 pico first second = 1 1,000,000,000,000 seconds (s).

1. The world is divided into 24 time zones. They are the Mid-Time Zone (Zero Time Zone), East 1-12 Zones, and West 1-12 Zones. Each time zone spans 15 degrees of longitude and the time is exactly 1 hour.

Finally, the 12th East and West Districts each span longitude degrees, bounded by 180 degrees east and west longitude. The time on the **meridian of each time zone is the time uniformly adopted in this time zone, which is called zone time. The difference in time between the two adjacent time zones is 1 hour.

2. For example, the time in the East 8 Zone of China is always 1 hour faster than the time in the East 7 Zone of Thailand, and 1 hour slower than the time in the East 9 Zone of Japan. Therefore, people who travel abroad must adjust their watches at all times to match the local time. Whenever you go west, you must move your watch forward by 1 hour for each time zone you pass (e.g. from 2 o'clock to 1 o'clock); Whenever you go east, you have to set your watch back by 1 hour (e.g. 1 o'clock to 2 o'clock) for each time zone you pass.

1 minute = 1 60 hours.

45 minutes = 3 4 hours = hours.

2 hours 45 minutes = (hours.)
