Calculate SAFE and convertible note conversion into equity at a financing close. Use when asked about SAFE conversion, note conversion, conversion shares, conversion math, how instruments convert in a priced round, or what happens to outstanding SAFEs and notes when a new round closes. Do NOT use for exit/sale/acquisition payouts at a sale price.
