Sugar Syrup Ratio Calculator
Calculate water and sugar ratios for simple, rich, and Demerara syrups by volume and weight.
Stellar luminosity — absolute magnitude ↔ solar luminosities
Convert star absolute magnitude to standard solar luminosity units (L⊙).
Thermal expansion coefficient — glaze fit calculation
Predict glaze-on-clay crazing or shivering by matching thermal expansion coefficients (COE).
Ink coverage — % coverage ↔ grams per sq meter
Estimate wet/dry printing ink consumption and layer weight based on sheet area and CMYK channel coverage percentages.
Solar irradiance — W/m² ↔ peak sun hours
Convert solar irradiance (W/m²) and daylight duration to Peak Sun Hours (PSH) and estimate daily solar panel system output.

Earthquake Magnitude (Richter ↔ Moment)
Convert and compare earthquake energy release, shaking amplitude, and felt effects between Richter (ML) and Moment Magnitude (Mw) scales.
Mohs Hardness & Scratch Resistance
Compare minerals, absolute hardness values, and scratch interactions using the classic 1-10 Mohs scale and Knoop indentation hardness.
Ore Grade & Concentration Converter
Convert mineral grade concentrations between grams per ton (g/t), weight percentage (%), troy ounces per ton (oz/st), and ppm.
Depth ↔ Geostatic & Hydrostatic Pressure
Determine lithostatic (rock overburden) and hydrostatic (fluid) pressure at custom geological underground depths or deep underwater.
