This document provides information about converting between units of measurement for mass and length. It includes examples of converting between metric and English units like kilograms, grams, pounds, and ounces. Activities have students identify appropriate measuring devices, convert between units, and solve problems involving conversions like determining how many kilograms a bridge can support given its maximum weight in tons. Answers are provided for the activities.

1. Least Mastered Skills:
Convert one unit of measure to another unit of measure.
SubTasks:
1.Identify the appropriate unit of measure for the given object.
2.Determine the best measuring device to use in each cases.
3.Change English unit to Metric unit of measure.

2. Overview
Which is heavy?..A rabbit weighing
2.2 pounds or a rabbit measures 1
kilogram?
Conversion from 1 unit to another
Metric Measures
1 milligram = = .001 g
1 centigram = 10 mg = .01 g
1 decigram = 10 cg = .1 g
1 gram = 10 dg = 1 g
1 dekagram = 10 g = 10 g
1 hectogram = 10 dag = 100 g
1 kilogram = 10 hg = 1000 g
1 metric ton = 1000kg =
English Measures
1 dram = 27.344 grains 1 ounce (oz)= 16 drams 1 pound (lb)= 16 ounces
1 kg= 2.2 lb
