Florida's FSA Mathematics Reference Sheets Packet (original is here)contains the conversions given here in each of its state tests from 4th grade through Algebra 2.
This chart (along with others equally scary) are included in Florida tests, which tells me that students do not have to remember them. That means that you can be called successful in Florida schools without knowing any of them. That is scary.
The following is from the Common Core State Standards Initiative in its materials for 4th grade (The red is mine):
"Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), ..."
Even Common Core is aware that some things just need to be known.
Is Florida the only state that thinks otherwise?
