Math & Numbers

Liter to Gallon

Convert liters to US liquid gallons with configurable decimal precision

Math & Numbers

Linear Programming Simplex Solver (Two-Phase)

Two-phase simplex for 2–6 variables and 1–8 ≤/≥/= constraints: Bland's rule, per-iteration pivot log, optimal/unbounded/infeasible status, and substitution checks.

Math & Numbers

Laplace Transform Calculator (Table Lookup)

Table lookup of L{f(t)} for 14 standard pairs, with parameter substitution, region of convergence, derivation note, and optional numeric F(s₀) evaluation.

Date & Time

Leap Second Table — IERS DUT1, TAI-UTC Offset & Cross-System Time

IERS leap-second history (27 insertions since 1972), current TAI-UTC offset (+37 s), DUT1 (UT1-UTC) notes, and POSIX/NTP/GPS/TAI/UT1 cross-system conversion for a given UTC instant

Math & Numbers

Kinematic Viscosity Converter (m²/s / cSt / ft²/s)

Convert kinematic viscosity (ν = dynamic viscosity / density) between m²/s (square metres per second, SI base), cSt (centistokes, 1 cSt = 1e-6 m²/s = 1 mm²/s), and ft²/s (square feet per second, 1 = 0.09290304 m²/s). Converts via m²/s to the target unit and also lists the equivalent value in all three units for reference. Reference values: water 20°C ≈ 1.004 cSt, SAE 30 oil ≈ 300–400 cSt at 40°C.

Math & Numbers

Lever Mechanical Advantage Calculator

Calculate the mechanical advantage of a lever and its output force. MA = L_in / L_out, and by moment balance F_out = F_in · MA. MA > 1 saves force; MA < 1 saves distance.

Math & Numbers

Kinetic Energy Calculator (KE = ½mv²)

Compute kinetic energy, mass, or velocity from the other two, with momentum and km/h conversion

Math & Numbers

LED Series Resistor Calculator

Compute the current-limiting resistor for LEDs in series with power, nearest standard value and wattage rating

Math & Numbers

KM/L to MPG

Convert kilometers per liter to miles per gallon with configurable decimal precision

Math & Numbers

L/100km to MPG

Convert liters per 100 kilometers to miles per gallon with configurable decimal precision

Math & Numbers

KPa to ATM

Convert kilopascals to standard atmospheres with configurable decimal precision

Math & Numbers

KPa to Bar

Convert kilopascals to bar with configurable decimal precision
