Percentages express parts per hundred; basis points (bps) express parts per ten thousand — common in finance for interest rate changes (25 bps = 0.25%). Decimals (0.05) and percentages (5%) represent the same ratio in different notation.
These conversions are simple multiplication but errors are costly in contracts and spreadsheets. Our tools convert decimal ↔ percent ↔ basis points ↔ parts per million without manual decimal shifting.

Real-world example
A rate hike of 25 basis points on a 4.00% loan means the new rate is 4.25%. Converting 25 bps = 0.25% avoids confusing basis points with percentage points.
