The Complete Unit Converter & Calculator Collection
Whether you need to convert ounces to milliliters for a recipe, calculate mortgage payments for a new home, or figure out how many kilometers are in a mile, ml2oz has the precise tool you need. Our collection covers over a thousand converters and calculators across every category you'll encounter in daily life.
Liquid & volume conversions
Liquid measurement is one of the most common conversion needs in cooking, bartending, science, and medicine. The confusion between US and UK measurements alone causes endless headaches — a US fluid ounce (29.5735 ml) differs from a UK fluid ounce (28.4131 ml), and a US cup (236.588 ml) differs from a UK cup (284.131 ml).
Our liquid converters handle every system: US customary (fl oz, cups, pints, quarts, gallons), UK imperial (imperial fl oz, imperial pints, imperial gallons), metric (ml, cl, dl, liters), and specialty units used in bars (shots, jiggers, fifths, handles) and pharmacies (drops, cc, mcg/ml).
Kitchen & cooking conversions
Cooking conversions are needed every day by home cooks scaling recipes up or down, following recipes from different countries, or substituting measuring tools. The most common kitchen conversions include:
- Cups to milliliters (1 US cup = 236.588 ml)
- Tablespoons to milliliters (1 tbsp = 14.787 ml)
- Teaspoons to grams (varies by ingredient density)
- Ounces to cups (8 fl oz = 1 cup)
- Fahrenheit to Celsius for oven temperatures
Length & distance conversions
Length conversions are essential for construction, travel, fitness, and science. The metric and imperial systems use fundamentally different base units — meters vs feet — making mental conversion difficult. Common conversions include centimeters to inches for clothing and body measurements, kilometers to miles for road distances, and feet to meters for building measurements.
Weight & mass conversions
Weight conversion is needed for cooking (grams to ounces), fitness (kilograms to pounds), shipping (pounds to kilograms), and medicine (milligrams to grams). The UK still uses stones for body weight, adding a third system to navigate alongside metric and US customary.
Temperature conversions
Fahrenheit and Celsius coexist in a world where the US uses °F and most other countries use °C. The exact conversion formula is °C = (°F − 32) × 5/9. Common reference points worth memorizing: 0°C = 32°F (water freezes), 100°C = 212°F (water boils), 37°C = 98.6°F (normal body temperature), and 180°C = 356°F (common baking temperature).
Finance calculators
Our finance calculator collection covers personal finance (budgeting, savings, debt payoff), mortgages and real estate (monthly payments, amortization, refinancing), investments (compound interest, ROI, CAGR), taxes (income tax, sales tax, VAT), salaries (hourly to annual, overtime, pay raises), retirement (401k, IRA, annuities), and business planning (break-even, profit margins, EBITDA).
Everyday life calculators
Beyond unit conversion, everyday calculations cover health (BMI, calorie needs, body fat), time (age, date differences, time zones), travel (fuel cost, drive time, flight distance), and household (electricity cost, paint coverage, flooring area). These tools remove the mental math from daily decisions.
