Conversion Basics How To Use Equalities To Convert Units Of Measure The system is: write the conversion as a fraction that equals 1. multiply it out (leaving all units in the answer) cancel any units that are both top and bottom. we can write the conversion as a fraction that equals 1: 1000 m 1 km = 1. and it is safe to multiply by 1 (does not affect the answer): 3 km × 1 = 3 km. When you’re first learning unit conversions, it helps to have a few basic guidelines. rule 1: when converting from a larger unit to a smaller unit, multiply. example: if you’re 5 feet tall and you want to know your height in inches, multiply: 5 x 12 = 60 inches. rule 2: when converting from a smaller unit to a larger unit, divide.
Conversion Basics How To Convert Units Of Measure With Equalities 10 mm=1 cm10 mm = 1 cm. multiply or divide. show step. look at the relationship in the original conversion. from millimeters to centimeters, the relationship is dividing by 10.10. divide 780780 millimeters by 10:10: 780 millimeters ÷10=78 centimeters 780 millimeters ÷ 10 = 78 centimeters. write the answer. Solution: since 1 mile = 1760 yards, multiply 15 miles by 1760 to determine the distance traveled in yards: 15 miles x 1760 yards mile = 26,400 yards. therefore, amy traveled 26,400 yards to visit her grandmother. example 3: using the unit conversion formula, find the height of a student 5'4" tall in meters. solution:. How many centimeters does the phone measure? use a conversion graph. solution: a conversion graph can be used to convert one quantity to another. take a graph sheet and the vertical axis indicates the centimeters and the values are the multiples of 2.54 because 1 inch is equal to 2.54 centimeters. and the horizontal axis indicates the inches. To convert units, verify that the two units you’re converting measure the same thing, like length or width, and look up the conversion rate for both units. next, write the conversion as a fraction, with the starting unit on the bottom and the unit you’re converting to on the top. then, multiply your original number by the fraction.

Example 1: converting units of time. convert 22 minutes to seconds. find the conversion factor. since seconds is the desired unit, you need the conversion factor between minutes and seconds: 1 minute = 60 seconds 1 minute = 60 seconds. the conversion factor for minutes and seconds is 60.60. Example: whether you have miles and need kilometers, or you have kilometers and need miles, you can use either conversion factor between miles and kilometers, namely 1 mi = 1.61 km or 1 km = 0.621 mi. either equation will work equally well. convert that equation to a fraction with the desired units on top and the given units on the bottom. more.
