Drug Concentration Converter
Convert pharmaceutical concentrations between % w/v, mg/mL, and mol/L using substance molecular weight presets.
Water hardness — ppm ↔ grains per gallon ↔ mg/L
Convert brewing water hardness profiles between ppm, mg/L, Grains per Gallon (gpg), and German degrees (dGH).
dB gain ↔ power ratio — amplifier and antenna specs
Convert logarithmic decibels (dB) to linear power and voltage ratios, or translate absolute power in Watts to dBm.
Salinity — PSU ↔ g/kg ↔ % — seawater concentration
Convert between Practical Salinity Units (PSU), salinity concentration in g/kg (ppt ‰), and percentage (%).
DPI Screen Density Sizing
Calculate typographic sizing differences across varying screen device densities and target DPI scopes.
PARACHUTING-SKYDIVING Utilities
Choose a specialized option to begin instant real-time conversion.
Freefall time — altitude ↔ seconds in freefall
Estimate freefall duration and terminal velocity based on exit altitude, deployment altitude, and body position.
Canopy size — jumper weight ↔ wing loading
Calculate wing loading (lbs/sq ft) and find recommended parachute canopy sizes based on total jumper exit weight.
Opening altitude — deployment + snivel time → safe height
Analyze deployment altitudes, parachute snivel time/distance, and safe canopy-open hard deck limits.
Drift calculation — wind speed ↔ canopy speed → landing offset
Calculate descent drift offset distance, wind deflection angles, and flight heading corrections for precision landing dropzones.
