Imperial measures.
The crew of the Storm Serpent are locked in a race against time as they navigate towards the hidden gold of Skull Rock. Their journey depends on quick, clever conversions between Imperial units—do you have what it takes to keep them on course?

🙂 = Correct, ☹️ = Incorrect

📌 Rules

• Imperial length conversions: Know the key ratios for measuring distances at sea and on land: 12 inches = 1 foot, 3 feet = 1 yard, and 1760 yards = 1 mile. To convert larger units to smaller units, multiply (e.g. 5 feet × 12 = 60 inches). To convert smaller units to larger units, divide.

• Imperial mass and capacity conversions: For weight, 16 ounces (oz) = 1 pound (lb) and 14 pounds = 1 stone. For liquid volume, 8 pints = 1 gallon. If the Storm Serpent carries 3 gallons of fresh water, multiply 3 × 8 = 24 pints.

💡 Tips

• Approximate metric equivalences: Keep these helpful benchmarks in mind for quick comparisons: 1 inch ≈ 2.5cm, 1 foot ≈ 30cm, 1 kilogram ≈ 2.2 lbs, and 1 gallon ≈ 4.5 litres (or 1 pint ≈ 568ml).

• Quick typing on our platform: Typing your answer is designed to be super quick and simple! Just type plain digits or decimals like 60 or 24 without adding any commas or spaces.

⚠️ Warnings

• Imperial units do not convert using tens, hundreds, or thousands: Unlike metric units, imperial measures do not use 10, 100, or 1000! Doing 10 inches = 1 foot or 100 pounds = 1 stone is a very common mistake.

• Watch the abbreviations: Make sure you do not mix up oz (ounces of mass) with liquid ounces, or lb (pounds) with currency. Always check whether the problem asks for length, mass, or volume.
