Pact Magic. If you have both the Spellcasting class
feature and the Pact Magic class feature from the warlock
class, you can use the spell slots you gain from the Pact
Magic feature to cast spells you know or have prepared
from classes with the Spellcasting class feature, and you
can use the spell slots you gain from the Spellcasting
class feature to cast w arlock spells you know.
于是我觉得没说可以的大概应该是不可以? 
这段话和我在说的有关系么?
有啊,因为契约魔法和施法是两回事,所以契约魔法的法术位和施法的法术位应该也是两回事,至于规则证据就是这段话做出的明确的区分 
也就是说,如果承认契约魔法的法术位不是施法的法术位,那么法位转能就应该不能用于契约魔法的法术位。
Converting a Spell Slot to Sorcery Points.
As a bonus action on your turn, you can expend
one spell slot and gain a number of sorcery points equal to the slot’s level.
Spell Slots
The Warlock table shows how many
spell slots you have. The table also shows what the level of those slots is; all of your spell slots are the same level. To cast one of your warlock spells of 1st level or higher, you must expend a spell slot. You regain all expended spell slots when you finish a short or long rest.
