### Units of time

Units of time measure how long something lasts. For example, how many seconds can you hold your breath, or how many minutes long is your favorite movie?

## How long are different units?

A

**second**is a short amount of time. It takes about $1$ second to turn on a light or open the refrigerator door.A

**minute**is equal to $60$ seconds. It takes about $1$ minute to brush your teeth.An

**hour**is equal to $60$ minutes. Extracurricular activities (gymnastics, piano lessons, soccer practice) often last about $1$ hour.*Want to learn more about units of time? Check out this video.*

## Converting larger units to smaller units

$1 \text{ minute} = \greenD{60}\text{ seconds}$

$1 \text{ hour} = \greenD{60}\text{ minutes}$

$1 \text{ hour} = \greenD{60}\text{ minutes}$

To convert larger units to smaller units we multiply the number of larger units by $\greenD{60}$.

**Example: Converting hours to minutes**

$1 \text{ hour} = \greenD{60}\text{ minutes}$

$\blueD{6} \text{ hours} = \blueD{6}\times \greenD{60}=360\text{ minutes}$

$\blueD{6} \text{ hours} = \blueD{6}\times \greenD{60}=360\text{ minutes}$

## Converting smaller units to larger units

To convert smaller units to larger units we divide the number of smaller units by $\greenD{60}$.

**Example: Converting seconds to minutes**
