Metricly

Metricly is the all-in-one technical unit converter and calculator built for people who need accurate results fast — whether you're on the job, in the lab, or in the kitchen.

WHAT MAKES METRICLY DIFFERENT
Most converter apps are basic. Metricly goes deeper — with full formula calculators, not just unit lookups. Enter any two values and get the rest calculated automatically.

ELECTRICAL
Ohm's Law calculator — enter any 2 of voltage, current, resistance or power and get the rest. Voltage, current, resistance and power conversions. Wire gauge (AWG to mm2). LED resistor calculator with nearest E12 standard value. Energy units including joules, kWh and BTU.

MECHANICAL
Torque (Nm, ft-lb, in-lb). Power (watts, kW, horsepower, metric HP). Pressure (Pa, kPa, bar, PSI, atm). Force (newtons, kgf, lbf). RPM to surface speed calculator. Compression ratio calculator.

HVAC AND PLUMBING
Temperature converter (Celsius, Fahrenheit, Kelvin) — type in any field and all others update instantly. Flow rate (L/min, GPM, m3/h, CFM). Thermal power (BTU, kW, tonnes of refrigeration). AC sizing calculator — enter room size and get BTU and kW required. Pipe sizing (DN to mm and inches).

CIVIL AND STRUCTURAL
Length, area and volume in metric and imperial. Stress and load (MPa, PSI, kN/m2, ksi). Concrete volume calculator with weight estimate. Steel flat bar weight calculator.

ELECTRONICS
Voltage divider calculator. RC time constant and cutoff frequency. Frequency to period converter. Capacitance, inductance and data storage units.

COOKING
Volume (cups, tablespoons, teaspoons, ml, litres, fluid oz — US, Australian and UK). Weight (g, kg, oz, lbs). Oven temperature converter with gas mark reference guide. Ingredient density converter — cups of flour, sugar, butter and over 20 ingredients converted to grams instantly.

STEM AND SCIENCE
Energy, speed, angle, time and data transfer rates. Scientific notation converter. Running pace converter (min/km to min/mile). BMI calculator in metric and imperial.

FULLY OFFLINE
Every conversion and calculation works without internet. No Wi-Fi needed, no data used, no account required.
