Convert time units

Learning Objectives Identify common time units (seconds, minutes, hours, days, weeks, years). Recall the standard conversion factors between different time units. Apply multiplication to convert larger time units to smaller time units. Apply division to convert smaller time units to larger time units. Use ratios and proportions to set up and solve time unit conversion problems. Solve real-world problems involving the conversion of time units. Ever wondered how many seconds are in your favorite 3-minute song? 🎶 Or how many hours until your next birthday? 🤔 In this lesson, you'll learn how to convert between different units of time, like seconds, minutes, hours, and days. Understanding these conversions is super useful for planning events, calculating travel times, and...

TermDefinitionExample Time UnitA standard measure used to quantify duration or the passage of time.Seconds, minutes, hours, and days are all examples of time units. Conversion FactorA ratio (fraction) used to convert a quantity from one unit to another without changing its value.The conversion factor between minutes and seconds is $\frac{60 \text{ seconds}}{1 \text{ minute}}$ or $\frac{1 \text{ minute}}{60 \text{ seconds}}$. RatioA comparison of two quantities by division, often expressed as a fraction or with a colon.The ratio of minutes to seconds is 1:60, meaning 1 minute for every 60 seconds. ProportionAn equation stating that two ratios are equal, used to solve for an unknown quantity in a conversion.$\frac{1 \text{ hour}}{60 \text{ minutes}} = \frac{2 \text{ hours}}{x \text{ minutes...

Basic Time Unit Equivalencies $1 \text{ minute} = 60 \text{ seconds}$ $1 \text{ hour} = 60 \text{ minutes}$ $1 \text{ day} = 24 \text{ hours}$ $1 \text{ week} = 7 \text{ days}$ $1 \text{ year} = 365 \text{ days}$ These are the fundamental relationships between common time units that you need to know for conversions. Converting Larger Units to Smaller Units (Multiply) $\text{Value in smaller unit} = \text{Value in larger unit} \times \text{Conversion Factor}$ When converting from a larger unit (e.g., hours) to a smaller unit (e.g., minutes), you will have more of the smaller units, so you multiply by the appropriate conversion factor. Converting Smaller Units to Larger Units (Divide) $\text{Value in larger unit} = \text{Value in smaller unit} \div \text{Conversion F...
