Corey measures the distance between two trees in his backyard. He finds that the measurement is 8 , but he wants to express the measurement in . How many centimeters are in 8 meters?
::科里测量了后院两棵树之间的距离。 他发现测量量为8, 但他想表达测量量。 8米内有多少厘米?In this concept, you will learn how to convert with metric units of measurements.
::在这个概念中,你将学会如何用计量单位转换。Converting Using Whole Number Values
::使用完整数字值转换L ength measures how long something is from one end to the other end.
::测量从一端到另一端的时间长度。Here are the common metric units of length from smallest to largest.
::以下是从最小到最大的通用指标单位。A millimeter is the smallest unit. Millimeters are most useful when measuring really tiny things. You can find millimeters on some rulers.
::毫米是最小的单位。 毫米在测量真正微小的东西时非常有用。 您可以在某些尺尺上找到毫米 。A centimeter is the next smallest unit. Centimeters can also be found on a ruler.
::一厘米是下一个最小的单位。在标尺上也可以找到厘米。A meter is a little more than 3 feet.
::一米比三英尺多一点A kilometer is used to measure longer distances.
::一公里用于测量更长的距离。Here is a chart to help with the conversions.
::这是帮助转换的图表 。Now that you know the conversions, you can change one unit to another unit.
::既然你知道这些转换, 你可以把一个单位换成另一个单位。5 km = ____ m
::5公里=______米You can convert larger units to smaller units by multiplying. There are 1000 meters in one kilometer.
::您可以通过乘法将大单位转换为小单位。 1公里内有1000米。The answer is 5000 m.
::答案是5000米Here's an example of converting smaller units to larger units.
::这是将小单位转换为大单位的一个例子。600 cm = ______ m
::600厘米=_____米You can convert smaller units to larger units by dividing. There are 100 cm in one meter.
::您可以通过除法将较小的单位转换为较大的单位。 以一米计有100厘米。600 100 6
The answer is 6 m.
::答案是6米Examples
::实例Example 1
::例1Earlier, you were given a problem about Corey's measurement of his tree.
::早些时候,你被问及 科里如何测量他的树。His measurement is 8 meters, but he wants to convert it to centimeters. How many centimeters are equal to 8 meters?
::他的测量量是8米,但他想把它转换成厘米。多少厘米等于8米?8 m = _____ cm
::8米=______厘米First, determine if the conversion is from smaller units to larger units or larger units to smaller units.
::首先,确定转换是从较小的单位改为较大的单位或较大的单位改为较小的单位。Larger to smaller
::从大到小Next, perform the appropriate operation.
::下一步,进行适当的操作。8 100
Then, write the value.
::然后,写下价值。800
The answer is 800 cm. The distance between the two trees is 800 cm.
::答案是800厘米。两棵树之间的距离是800厘米。Example 2
::例2Find the equivalent metric measurement.
::寻找同等的衡量尺度。6 m = ______ mm
::6米=_____毫米First, determine if the conversion is from smaller units to larger units or larger units to smaller units.
::首先,确定转换是从较小的单位改为较大的单位或较大的单位改为较小的单位。Larger to smaller
::从大到小Next, perform the appropriate operation.
::下一步,进行适当的操作。6 1000
Then, write the value.
::然后,写下价值。6000
The answer is 6000 mm.
::答案是6000毫米Example 3
::例3Find the equivalent metric measurement.
::寻找同等的衡量尺度。2000 mm = ______ cm
::2000毫米 = 厘米First, determine if the conversion is from smaller units to larger units or larger units to smaller units.
::首先,确定转换是从较小的单位改为较大的单位或较大的单位改为较小的单位。Smaller to larger
::从小到大Next, perform the appropriate operation.
::下一步,进行适当的操作。2000 10
Then, write the value.
::然后,写下价值。200
The answer is 200 cm.
::答案是200厘米Example 4
::例4Find the equivalent metric measurement.
::寻找同等的衡量尺度。3 km = _____ m
::3公里=______米First, determine if the conversion is from smaller units to larger units or larger units to smaller units.
::首先,确定转换是从较小的单位改为较大的单位或较大的单位改为较小的单位。Larger to smaller
::从大到小Next, perform the appropriate operation.
::下一步,进行适当的操作。3 1000
Then, write the value.
::然后,写下价值。3000
The answer is 3000 m.
::答案是3000米Example 5
::例5Find the equivalent metric measurement.
::寻找同等的衡量尺度。4000 cm = ______ m
::4000厘米=_____米First, determine if the conversion is from smaller units to larger units or larger units to smaller units.
::首先,确定转换是从较小的单位改为较大的单位或较大的单位改为较小的单位。Smaller to larger
::从小到大Next, perform the appropriate operation.
::下一步,进行适当的操作。4000 100
Then, write the value.
::然后,写下价值。40
The answer is 40 m.
::答案是40米Review
