Grain

What is a grain?

The grain (gr) equals 1/7000 of an avoirdupois pound, about 64.8 milligrams.

Origin of the grain

Based on the nominal mass of a single barley grain.

Where it is used

Ammunition and bullet mass, archery, and historical pharmacy.

When and where it was developed

Standardized through the English avoirdupois system and retained in 1959.

Kilopound (kip)

What is a kilopound (kip)?

The kilopound, or kip, equals 1,000 pounds, about 453.6 kilograms.

Origin of the kilopound (kip)

A blend of 'kilo' and 'pound'; the contraction 'kip' is widely used.

Where it is used

Structural and civil engineering loads in the United States.

When and where it was developed

Adopted in 20th-century US engineering practice.

Grain to Kilopound (kip) conversion formula

The relationship between grains and kilopounds (kip):

1 gr = 1.428571e-7 kip
1 kip = 7000001.0802652519 gr

To convert grains to kilopounds (kip), multiply the value in grains by 1.428571e-7. To reverse, multiply kilopounds (kip) by 7000001.0802652519.

Type a value into the calculator. The result in kilopounds (kip) updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Kilopound (kip) to Grain converter for the reverse direction.

Step-by-step: convert grains to kilopounds (kip)

  1. Write down the value in grains (gr).
  2. Multiply that value by the factor 1.428571e-7.
  3. The product is the equivalent value in kilopounds (kip) (kip).
  4. To reverse, multiply the kilopound (kip) value by 7000001.0802652519.

Worked examples

Example 1 — Convert 1 gr to kip:
1 × 1.428571e-7 = 1.428571e-7 kip

Example 2 — Convert 100 gr to kip:
100 × 1.428571e-7 = 1.428571e-5 kip

Real-world example — Paper and film thicknesses

At the thickness of office paper (roughly 3 grains), converting between sub-millimeter units is routine for packaging and printing buyers comparing quotes from metric and US suppliers.

3 gr × 1.428571e-7 = 4.285714e-7 kip

Real-world example — Plastic-film thickness alternates

A 150-grain plastic film converts cleanly to kilopounds (kip) — useful for packaging buyers reconciling supplier datasheets across metric and US measurement systems.

150 gr × 1.428571e-7 = 2.142857e-5 kip

Real-world example — Hair-width scale measurements

A 70-grain measurement (about the diameter of a human hair) is the kind of value materials engineers regularly express in adjacent micro-scale units like kilopounds (kip) for direct comparison across supplier datasheets.

70 gr × 1.428571e-7 = 9.999998e-6 kip
