YOUR LEVEL after checking HW & asking questions on 9-1a/b Literal Equations & Temperature Conversion? a.) 0 – totally lost b.) 1 – with a lot of help I can get it c.) 2 – I need some help d.) 3 – I only need a tiny clarification e.) 4 – Zip It Mr. Wiz, I got this! Where are you????
9-2a Convert Length, Weight/Mass, Capacity, & Time MA.8.G.5.1 … Compare, contrast, and convert units of measure between different measurement systems (US customary or metric (SI)) and dimensions including temperature, area, volume, and derived units to solve problems. Learning Goals: -Convert customary and metric units of length, weight or mass, capacity, and time
Unit Ratio - A ratio in which the denominator is 1 unit Examples:
Dimensional Analysis - Includes units of measurements as factors ex: 52 ft = ? yd Always put the unit you are converting to in the numerator 52 ft 52 ft = 17.3 yd The ft units cross cancel when they are at a diagonal while multiplying fractions
Now you try!!!! Dimensional Analysis 26,513 ft = ? mi a.) 139988640 b.) .199 c.) 5.02 d.) 199.1 e.) 14.0 f.) 7.34
Now you try!!!! Dimensional Analysis 26,513 ft = ? mi Always put the unit you are converting to in the numerator 26,513 ft 26,513 ft = 5.02 mi
Now you try!!!! Dimensional Analysis 26 qt= ? gal a.) 6.5 gal b.) 8.2 gal c.) 104 gal d.) 10.4 gal e.) 6.3 gal f.) 7.6 gal
Now you try!!!! Dimensional Analysis 26 qt = ? gal 26 qt 26 qt = 6.5 gal
NOW YOU TRY!!!! Convert TIME 43 min = ? Days a.) 30 days b.) .3 days c.) .43 days d.) 43 days e.) .030 days f.) It isn’t any days
NOW YOU TRY!!!! Convert TIME 43 min = ? days 43 min 43 min .030 days
Convert BETWEEN SYSTEMS Sometimes, you need to convert between units in the customary system and units in the metric system. Just follow the SAME process and you’ll be okay! ex: 15.3 ft = ? cm 15.3 ft 15.3 ft466.3 cm
Convert BETWEEN SYSTEMS 23,450 cm = ? yd 23,450 cm 2256.5 yd
Now YOU TRY!!!! Convert BETWEEN SYSTEMS 14,250 mL = ? gal a.) 376 gal b.) 3785 gal c.) 14.3 gal d.) 3.76 gal e.) 5393.6 gal f.) 53.9 gal
Now YOU TRY!!!! Convert BETWEEN SYSTEMS 14,250 mL = ? gal 14,250 ml 13.76 gal
9-2b Convert Rates MA.8.G.5.1 … Compare, contrast, and convert units of measure between different measurement systems (US customary or metric (SI)) and dimensions including temperature, area, volume, and derived units to solve problems. Learning Goals: -Convert rates using dimensional analysis
A rate is a ratio that compares two quantities with different types of units such as 30 miles in 2 hours or $3.99 for 2 pounds. A derived unit is a unit that is made from a measurement system base unit, such as length, mass, or time. Examples of these units could be square meter or miles per hour. Examples of derived units formed from rates:
Convert RATES Sometimes, you need to convert between Rates. Just follow a similar process and you’ll be okay! mi/h= ? ft/s You must be sure that the unit you are cancelling is diagonal to the original unit mi/h80.7 ft/s
NOW YOU TRY!!!! Convert RATES l = ? kg/cm a.) 63.4 b.) 84.5 c.) 409.0 d.) 13.1 e.) 68.2 f.) 57.3
NOW YOU TRY!!!! Convert RATES l = ? kg/cm 13.1 kg/cm
