A new measurements post! In this case we are going to talk about time measurement. How can we** measure time**? What units are used?

The tool used to measure time is the clock. The unit that we use as a reference is the day. Regarding the day, there are units of time that are smaller than the day, and there are other units of time that are greater than the day.

**Units Smaller Than The Day:**

- A
**day**has**24 hours.** - One
**hour**has**60 minutes**. - A
**minute**has**60 seconds**.

**Units Larger Than The Day:**

**7 days**are one**week.****Between 28 and 31 days**are one**month.****12 months**form one**year.****10 years**form a**decade.****100 years**form a**century.**

There are many more units used to **measure time**, but these are the most common.

*How can we change from one unit of time to another?
*In the next picture you can see that to go from hours to minutes or to change from minutes to seconds, you must multiply by 60. On the other hand, to change from seconds to minutes or from minutes to hours, one must divide by 60.

**Time Measurement Examples:**

**How many minutes are 1000 seconds? **To move from seconds to minutes, one must divide by 60.

1000/ 60 = 16 and 40 remain.

This means that 1000 seconds is equal to **16 minutes and 40 seconds.**

**How many minutes are in three hours? **To go from hours to minutes we will have to multiply by 60.

3 x 60 = 180

3 hours is equal to** 180 minutes**

**How many hours are 250,000 seconds?*** To move from seconds to hours one must divide by 60 twice.
*

250000÷60 = 4166 and 40 is remaining.

This means we have 4166 minutes and 40 seconds. Now we return to divide 60 minutes.

4166÷60 = 69 and the remainder is 26.

At the end we find that 250,000 seconds are the same as

**69 hours, 26 minutes and 40 seconds.**
