        ? throw _conversionException('.toQuantity()', results)
        : results.first is ValidatedQuantity
            ? [results.first]
            : results.first is num
                ? [
                    ValidatedQuantity(
                        value:
                            UcumDecimal.fromString(results.first.toString()),
                        unit: '1')

                : results.first is String
