Convert Hop (홉) to Milliliters (mL)

How Hop relates to milliliters (1 hop = 180mL)

The hop (홉) is a small traditional volume unit equal to one-tenth of a doe, or exactly 180mL. To convert hop to milliliters, multiply the hop value by 180. For example, 2 hop = 360mL and 5 hop = 900mL. Ten hop equals 1800mL, which is exactly one doe (1.8L). Since a shot of soju is roughly 50mL, one hop is about three to four soju shots. For hop-to-milliliter conversion, just remember to multiply by 180.

When Koreans search for this

Old cookbooks and traditional liquor recipes often list small ingredient amounts by the hop, which need converting to milliliters today. When brewing cheongju, yakju, or fruit wine, the amount of yeast starter or water may be given in hop and must be moved into a measuring cup. It's also used to check the real amount when cooking a small pot of rice or porridge from one or two hop of rice. Many people want to know 'how much is one hop' when buying sesame or perilla oil in small quantities. The hop is the traditional unit that appears most often when handling amounts smaller than a doe.

Reference points and a caution

The easy anchors are 1 hop = 180mL and 10 hop = 1 doe = 1800mL. A paper cup holds roughly 180-200mL, so one hop is close to a paper cup's worth. The caution is that 'hop' is a volume unit — one hop of rice is 180mL by volume but weighs about 160g (one-tenth of a doe's 1.6kg). Water at 180mL weighs about 180g, but rice has air gaps between the kernels, so the same volume weighs differently. When handling rice by the hop, keep volume (mL) and weight (g) as separate ideas.
