Select and use an appropriate unit of measurement for a given attribute (length, mass, liquid volume, time) within
one system of units: metric - km, m, cm; kg, g, l, ml; customary - lb, oz; time - hr, min, sec.

Within one system of units, express measurements of a larger unit in terms of a smaller unit. Record
measurement equivalents in a two-column table.

New York State Next Generation Learning Standards:
4.MD.1

Know relative sizes of measurement units: ft., in.; km, m, cm e.g., An inch is about the distance from the tip of your thumb to your first knuckle. A foot is the length of two dollar bills. A meter is about the height of a kitchen counter. A kilometer is 2 1/2 laps around most tracks. Know the conversion factor and use it to convert measurements in a larger unit in terms of a smaller unit: ft., in.; km, m, cm; hr., min., sec. e.g., Know that 1 ft. is 12 times as long as 1 in. and express the length of a 4 ft. snake as 48 in. Given the conversion factor, convert all other measurements within a single system of measurement from a larger unit to a smaller unit. e.g., Given the conversion factors, convert kilograms to grams, pounds to ounces, or liters to milliliters. Record measurement equivalents in a two-column table. e.g., Generate a conversion table for feet and inches.

Ohio's Learning Standards:
4.MD.1

Know relative sizes of the metric measurement units within one system of units. Metric units include kilometer, meter, centimeter, and millimeter; kilogram and gram; and liter and milliliter. Express a larger measurement unit in terms of a smaller unit. Record measurement conversions in a two-column table.For example, express the length of a 4-meter rope in centimeters. Because 1 meter is 100 times as long as a 1 centimeter, a two-column table of meters and centimeters includes the number pairs 1 and 100, 2 and 200, 3 and 300, ... * * Learning Farm includes imperial units in addition to metric units.<

4th Grade Math - Convert Units Lesson

CONVERTING UNITS

to convert from smaller units to larger units → divide

to convert from larger units to smaller units → multiply

Example:

There are 1,000 meters in 1 kilometer. To convert kilometers to meters, multiply the number of kilometers by 1,000.
