Tips for an accurate result
Keep to one measurement system (metric or US customary) throughout a recipe to avoid small rounding errors compounding.
Scale a recipe in one pass rather than doubling twice — repeated rounding across multiple scaling steps adds up.
When converting a recipe between systems, convert the whole recipe at once and write it down, rather than converting each measurement on the fly while cooking.
Some ingredients (leavening agents, spices) don't scale linearly with the rest of a recipe — adjust those to taste rather than by strict ratio.
