liters per minute to liters per second

Process engineers size pumps in liters per minute; hydraulic modelers and fire codes think in liters per second. The bridge is 0.0166666666667 — one sixtieth, the exact fraction of a liter per second in a liter per minute. A 30 L/min lab pump is 0.5 L/s; a 600 L/min process line is 10 L/s. The factor is the reciprocal of 60, and it is exact even though its decimal never ends.

liters per minute to liters per second

One L/min is 1/60 L/s = 0.0166666666667 L/s, by definition — the liter is unchanged, only the time base moves from minutes to seconds. The repeating decimal is the decimal signature of a factor built from 60, and it is exact to every digit. Laboratory dosing pumps, small process lines, and hydraulic models all convert between these two scales, and because the factor is definitional, the 0.016667 never carries measurement error — only rounding error if you cut it short.

liters per second = liters per minute × 0.0166666666667
1 L/min = 0.0166666666667 L/s — 1 ÷ 60 seconds
The factor is exact: the reciprocal of 60.

Engineering Context

The only anchor this page needs is the time family's second — the liter is identical on both sides. The L/s to L/min page runs it backward, and the flow rate hub collects the full family. Dosing and process work also connect to the volume pages when batch totals are computed from flow over time.

Frequently Asked Questions

How many L/s is 1 L/min?

Exactly 0.0166666666667. It is 1/60 by definition — the same liter, one sixtieth of the flow per second.

Why does the conversion need so many digits?

Because the factor is the reciprocal of 60, which is a repeating decimal: 1/60 = 0.01666... It is exact, not approximate — you just need enough digits to avoid rounding drift in large flows.

When should I use L/s instead of L/min?

Use L/s when flows are large enough that L/min becomes a four-digit number (fire, storm, canal), and L/min for equipment-level process work. The two are the same flow at different time bases.
