Math & rounding

[LNS95, BSN]

Quick question about rounding! In school we were taught that the only time you round *during* the equation is lbs to kg (round to nearest tenth). On UWorld I got a question wrong because rounding kg to one decimal place ended up changing the answer, their example calculation did not round. For the NCLEX, should I continue to round kg during the calculation?

Example: For 190 lbs I would use 86.4 as the weight when calculating dose (instead of 86.3636....)
