| First of all, "hectometer" is unambiguously misspelled here—the prefix is "hecto-", not "hecta-". You should also accept the spellings "metre" and "litre", which are standard spellings in the United Kingdom and elsewhere (along with the corresponding spellings for derived units, such as "centimetre" and "millilitre"). Be consistent with your spelling of the prefix "deka-" or "deca-"; both spellings are acceptable, and both should be accepted, but currently the displayed answers and the answers you accept are inconsistent (you are displaying and accepting only "deca-" for length and only "deka-" for mass and volume). Finally, "megagram" should be acceptable for metric ton, as that is the proper name for it (though it is not as commonly used). |
