How much marjoram do you use to replace 1 teaspoon of sage?

To replace 1 teaspoon of sage with marjoram, use about 1 to 1.5 teaspoons of dried marjoram. Marjoram has a milder flavor than sage, so starting with a smaller amount and adjusting to taste is recommended. If using fresh marjoram, you might need to double the amount, as fresh herbs are less concentrated.
