Cholesterol Unit Converter vs Ohmica

No fuss cholesterol unit calculator. Fast conversion from mg/dL to mmol/L and vice versa. Simply enter mmol/L or mg/dL value you wish to convert: mg/dL --- mmol/L mmol/L --- mg/dL Quick and easy. It does what it says on the tin.

Ohmica — The Electronics Calculator Your Multimeter Doesn't Have Most electronics calculators give you a result. Ohmica shows the result, the formula behind it, the substituted values, and the assumptions used. Because when you're working on a real circuit, understanding the math matters. Built for Arduino, ESP32, Raspberry Pi, makers, technicians, electronics hobbyists, and engineers, Ohmica helps you solve real-world electronics problems quickly and confidently. WHY OHMICA • Shows the actual formula used for every calculation • Displays substituted values for transparency • Supports engineering notation such as 4k7, 100nF, and 20mA • Works completely offline • No account required • No ads • Available in English and Vietnamese Unlike generic calculators, Ohmica lets you verify the model behind the result. For example, when calculating voltage drop, Ohmica can show: Vdrop = 500 mA × 847 mΩ (AWG 14, Copper, 40 m Total Run) You immediately know which assumptions were used and can validate the result with confidence. CORE CALCULATORS Fundamentals • Ohm's Law • LED Resistor • Voltage Divider • Resistor Color Code Passive Components • Series / Parallel Resistance • Series / Parallel Capacitance • RC Time Constant • Capacitor Code • Inductor Code Power & Wiring • AWG Reference • Voltage Drop • Battery Runtime • PCB Trace Width • LED Strip Power Digital & Control • PWM & Frequency • I²C Pull-up Resistor • 555 Timer REFERENCES • ESP32 Pinout • Arduino Uno Pinout • Raspberry Pi GPIO • RJ45 T568A / T568B • Common I²C Addresses • SI Prefix Reference Every tool is designed for practical electronics work rather than classroom exercises. Whether you're designing an ESP32 project, sizing LED resistors, checking voltage drop, calculating RC timing, or selecting PCB trace widths, Ohmica helps you get answers without opening a browser or doing calculations by hand.
