How do riichi mahjong points convert to money? Riichi mahjong points convert to money through an agreed rate per 1,000 points, applied to each player's final score after uma (placement bonuses). Japanese parlor culture names the common rates: tenpin is 100 yen per 1,000 points, tengo is 50. A home table can pick any rate — at 10 cents per 1,000 points, a typical session swings a few dollars per player.

Riichi mahjong points convert to money through an agreed rate per 1,000 points, applied to each player's final score after uma (placement bonuses). Japanese parlor culture names the common rates: tenpin is 100 yen per 1,000 points, tengo is 50.

Detailed Answer
Short answer: Riichi points become money by multiplying each player's final plus-or-minus score by an agreed rate per 1,000 points. The rate is set before the first hand, and the conversion happens once, at the end of the session — not hand by hand.
The conversion formula:
Because the four adjusted scores always sum to zero, the four money results do too — that's your error check.
The named rates: Japanese parlor culture has shorthand for common rates: **tensan** (30 yen per 1,000 points), **tengo** (50 yen), and **tenpin** (100 yen), with tenpin the typical parlor standard. Clubs outside Japan simply agree a rate in local currency — 10 or 25 cents per 1,000 points are common low-stakes choices for home tables.
A worked example at 10 cents per 1,000: Four players finish a hanchan at 42,300 / 28,800 / 18,200 / 10,700 points. Relative to the 25,000 start, that's +17.3k / +3.8k / −6.8k / −14.3k. Applying a 10–20 uma gives +37.3k / +13.8k / −16.8k / −34.3k. At 10 cents per 1,000, the night settles at +$3.73 / +$1.38 / −$1.68 / −$3.43 — a friendly evening even after a heavy loss, which is why riichi is the gentlest money game of the major mahjong variants.
Many riichi tables skip money entirely. Riichi's economy already lives in the points — sanctioned competition is points-only, and plenty of clubs treat final standings as the result. Money conversion is strictly optional and always the table's choice.
Tracking it at a real table: A money-only ledger app like PartyPot fits riichi cleanly precisely because it doesn't try to score the game. Your table counts han and fu and moves the points with sticks or a scoring app as usual; at the end, you enter each player's converted result (or transfer the amounts as you go) and the app settles who pays who in the fewest transfers. Players set their own values, so the same setup works for tenpin-style stakes, dime-per-thousand home rates, or pure points with no money at all.
