Measurement Lab Problem: How do you decide which sl prefix to use when measuring an item Introduction Use everyday household items to complete the following measurements. many decimal places instrumentallows se decimal based on the measuring lines. The more if necessary, points you use, the more precise the measurement. You items but you must note what can substitute instead of a phone book denote this in you make mple, if you use a textbook the unit conversions, refer your data table). unsure abou complete back to the content in the module. Materials Needed: metric ruler, measuring tape, or meter stick 2 different size cups bathroom scale that can weigh items at least between 1 and 20 pounds. measuring cup telephone book full two liter bottle or gallon of milk large pot or pan Procedure: Perform the following measurements. create a data table showing your measured data and conversions for each type of measurement. Show the calculations that you used for conversion under each data table. Distance 1. Measure the following items in centimeters (cm): a. length of a table b. length of the room the table is in c. width of the same room 2. Using conversion factors, convert these measurements into meters (m) and kilometers (km) Volume 1. Pour water into two different sized cups. The exact amount is not important, but 2. about 3/4 full is best. cup and measure the volume in Pour the water from one cup into a measuring milliliters (ml). 3. Pour that water down the sink. water from the second cup into the measuring cup and measure its 4. Now pour the 5. volume in mL measurements Using conversion factors, convert these into liters (L) and decaliters (dal)
Distance
1
a.Length of the table = 101.56cm
b. Length of the room = 1010.45cm
c. Width of the room = 985.36cm
100centi meters =1meter. to convert cm into meters divide cm with 100.
1000meters = 1kilo meter. to convert cm into km divide cm with 10000.
2. Conversion into meters and kilometers
Length of the table = 1.0156meters or 0.0010156 km
Length of the room = 10.1045meters or 0.0101045km
Width of the room = 9.8536meters or 0.0098536km
Volume
Cup 1 volume = 130.5 ml
Cup 2 volume = 170.4 ml
1000ml = 1 litre. to convert ml into litres divide ml with 1000.
10000ml = 1 decalitre or 10 litres = 1 decalitre. to convert ml into decalitre divide ml with 10000.
Cup 1 volume 130.5ml = 0.1305litres or 0.01305decalitres
Cup 2 volume 170.4ml = 0.1704litres or 0.01704decalitres.
Mass
Weight of telephone book = 1.5lbs
Weight of 2 litre bottle = 4.43 lbs
Weight of large pot or pan = 12.34 lbs
1lb = 0.453592 kilograms or 453.592 grams
1000grams = 1kilogram.
To convert lbs into kg multiply lbs with 0.453592
To convert lbs into grams multiply lbs with 453.592
Weight of telephone book = 0.680388kg or 680.388grams
Weight of 2 litre bottle = 2.00941256 kg or 2009.41256 grams
Weight of large pot or pan = 5.59732528kg or 5597.32528grams
