Formula feeding questions.

My daughter is 7.5 weeks old and we are switching to formula. Up to now she was eating 3 oz of breastmilk every 2-2.5 hours during the day and 4 oz at night. Now that we switched to formula I’m wondering should she be eating the same? I ask because I’ve seen that babies don’t need as much formula as they eat in breast milk. I’m also wondering if I should be spacing out her feedings. Should I try 4 oz of formula every 3-4 hours instead of feeding every 2-3? FTM so please no judgement if these are dumb questions 😊
