Both the Metric and English systems use the same units of measurement for time. Same with most conversions, the conversion table for units of time should familiarized.

Below is the conversion table of the units of time.

Equivalent |
---|

1 min = 60 s |

1 hr = 60 min |

1 d = 24 hrs |

1 wk = 7 d |

1 mo = 30 d |

1 yr = 12 mos = 365 days |

1 decade = 10 yrs |

1 century = 100 yrs |

1 millennium = 1000 yrs |

To convert units of measurement for time, here are the steps.

**Step #1:** Identify the units used.

**Step #2:** Determine the relationship between the units.

**Step #3:** Determine the conversion factor (in fraction form).

The denominator should have the same unit as the original measurement.

**Step #4:** Multiply the original measurement by the conversion factor.

**Step #1:**Determine the units used.

The units are **seconds (s)** and **minutes (min)**.

**Step #2:** Determine the relationship between the units.

**1 min = 60 s**

**Step #3:** Determine the conversion factor (in fraction form).

Take note that the denominator should have the same unit as the original measurement.

The original measurement is in seconds.

So, the denominator of the conversion ratio should be in seconds.

The conversion factor is `(1 min) / (60 s)`

**Step #4:** Multiply the original measurement by the conversion factor.

`300 s ` x `(1 min)/(60 s)`= `5 min`

Therefore, 300 s = **5 min**

**Step #1:**Determine the units used.

The units are **days (d)** and **hours (hr)**.

**Step #2:** Determine the relationship between the units.

**1 d = 24 hrs**

**Step #3:** Determine the conversion factor (in fraction form).

Take note that the denominator should have the same unit as the original measurement.

The original measurement is in days.

So, the denominator of the conversion ratio should be in days.

The conversion factor is `(24 hrs) / (1 d)`

**Step #4:** Multiply the original measurement by the conversion factor.

`4 d ` x `(24 hrs)/(1 d)`= `96 hrs`

Therefore, 4 d = **96 hrs**

**Step #1:**Determine the units used.

The units are **weeks (wk)** and **days (d)**.

**Step #2:** Determine the relationship between the units.

**1 wk = 7 d**

**Step #3:** Determine the conversion factor (in fraction form).

Take note that the denominator should have the same unit as the original measurement.

The original measurement is in weeks.

So, the denominator of the conversion ratio should be in weeks.

The conversion factor is `(7 d) / (1 wk)`

**Step #4:** Multiply the original measurement by the conversion factor.

`6 wk ` x `(7 d) / (1 wk)`= `42 d`

Therefore, 6 wk = **42 d**

**Step #1:**Determine the units used.

The units are **months (mo)** and **years (yr)**.

**Step #2:** Determine the relationship between the units.

**1 yr = 12 mo**

**Step #3:** Determine the conversion factor (in fraction form).

Take note that the denominator should have the same unit as the original measurement.

The original measurement is in months.

So, the denominator of the conversion ratio should be in months.

The conversion factor is `(1 yr) / (12 mo)`

**Step #4:** Multiply the original measurement by the conversion factor.

`18 mo ` x `(1 yr) / (12 mo)`= 1 `1/2` yrs

Therefore, 18 mo = **1 `1/2` yrs**
