Quick answer

To convert units, multiply by the conversion factor between them: 1 inch = 2.54 cm exactly, 1 kg ≈ 2.2046 lb, °F = °C × 9/5 + 32. For storage, 1 GB is 1,000,000,000 bytes in the decimal (SI) system used by drive makers, while 1 GiB is 1,073,741,824 bytes in the binary system many operating systems use.

Conversion factors worth remembering

Length: 1 inch = 2.54 cm; 1 foot = 30.48 cm; 1 mile = 1.609344 km.
Mass: 1 kg = 2.20462 lb; 1 lb = 453.592 g; 1 stone = 14 lb (≈ 6.35 kg).
Temperature: °F = °C × 9/5 + 32; °C = (°F − 32) × 5/9; K = °C + 273.15.
Speed: 1 km/h = 0.621371 mph; 1 mph = 1.609344 km/h.
Storage: 1 KB = 1,000 bytes (SI) vs 1 KiB = 1,024 bytes (binary).

Why your 1 TB drive shows about 931 GB

Drive manufacturers use decimal units (1 TB = 10¹² bytes), but Windows reports sizes in binary units (dividing by 1,024 repeatedly) while still labelling them “GB”. 10¹² ÷ 1,024³ ≈ 931, so no space is missing.

Frequently asked questions

How many bytes are in a gigabyte?

In the decimal (SI) definition used by storage makers, 1 GB = 1,000,000,000 bytes. In the binary definition, 1 GiB = 1,073,741,824 bytes (1,024³).

How do I convert Celsius to Fahrenheit?

Multiply by 9/5 and add 32. 25 °C = 25 × 1.8 + 32 = 77 °F.

How many centimetres are in an inch?

Exactly 2.54 cm — this is the international definition of the inch.

How many pounds are in a kilogram?

About 2.20462 lb. The pound is defined as exactly 0.45359237 kg.

Why does my 1 TB drive show 931 GB?

The drive uses decimal terabytes; the operating system reports binary units. The capacity is the same, just counted differently.
