Cooking units cheat-sheet
- 1 cup = 200 ml (Korean / Japanese standard; US cup ≈ 240 ml)
- 1 tablespoon (T) = 15 ml
- 1 teaspoon (t) = 5 ml ≈ 1/3 of 1 tablespoon
- 1 pinch ≈ 0.5–1 g
- 1 handful ≈ 30–50 g
- 1 garlic clove ≈ 4–5 g (≈ 1 teaspoon when minced)
- Oven F↔C:
C = (F − 32) ÷ 1.8· 350°F ≈ 175°C, 400°F ≈ 200°C

FAQ
Is 1 cup 200ml or 240ml here?
This tool uses the Korean standard 1 cup = 200ml. US recipes often assume 240ml — convert to ml first if you need that precision.
Tablespoon and teaspoon sizes?
1 tablespoon = 15ml and 1 teaspoon = 5ml in Korean, US, and Japanese cooking — the same.
I see "2.67 tbsp" — what does that mean?
Common ratios like 0.25 / 0.33 / 0.5 / 0.66 / 0.75 are displayed as 1/4, 1/3, 1/2, 2/3, 3/4. Anything else falls back to a decimal — round it up or down as you cook.
What about "pieces" or "pinches"?
Non-standard units (pcs, pinch, clove, handful) are simply multiplied. "1.5 onions" means "use 1 or 2" in practice.
Is anything sent to a server?
No. Calculations stay in your browser; your recipe is auto-saved in localStorage so it persists between visits.
