Quick Answer

400 grams of yogurt is approximately 1.6 to 1.7 cups (about 1⅔ cups).

Why This Conversion Works

Yogurt is slightly denser than water, so:

  • 1 cup of yogurt ≈ 240–250 grams
  • Using an average (245 g per cup):
    400÷245≈1.63400\div 245\approx 1.63400÷245≈1.63 cups

Practical Kitchen Guide

If you are measuring without a scale:

  • 1½ cups = slightly under 400 g
  • 1⅔ cups = very close to 400 g
  • 1¾ cups = slightly over

Small Tip

Thickness matters a bit:

  • Greek yogurt (thicker): may weigh slightly more per cup
  • Regular yogurt: closer to the average used above

For most recipes, 1⅔ cups is accurate enough and will not affect results noticeably.
