A few sample questions
1. How many inches are in one foot?
Answer: 12 inches
One foot equals exactly 12 inches — a standard that has been used in the United States and United Kingdom for centuries. The word 'foot' originally came from the length of a human foot.
2. How many days are in a leap year?
Answer: 366 days
A leap year has 366 days because an extra day — February 29 — is added to keep our calendar aligned with Earth's orbit around the Sun, which takes about 365.25 days.
3. How many seconds are in one minute?
Answer: 60 seconds
There are 60 seconds in one minute. This base-60 system for time was inherited from the ancient Babylonians, who used a counting system based on the number 60.
4. On the Fahrenheit scale, at what temperature does water freeze?
Answer: 32°F
Water freezes at 32 degrees Fahrenheit, which is the same as 0 degrees Celsius. Water boils at 212°F (100°C) at sea level.
5. How many feet are in one mile?
Answer: 5,280 feet
One mile equals exactly 5,280 feet. This odd number dates back to the Roman 'mille passuum' (a thousand paces), which was later adjusted to fit neatly into the English furlong system.
Things you'll learn along the way
- February is the shortest month, with just 28 days in a regular year and 29 in a leap year. All other months have 30 or 31 days.
- There are 16 ounces in one pound. This is the avoirdupois system used in the United States for everyday weights like groceries and body weight.
- A full day (one Earth rotation) has 24 hours, which is why clocks cycle around twice each day. Ancient Egyptians were among the first to divide the day into 24 equal parts.
