Ounces-force to Pounds-force Converter

To convert a measurement in ounces-force to pounds-force, multiply the value by 0.0625. The conversion factor comes from the relationship between both units and the newton.

For example, to convert 5 ozf to pounds-force: 5 × 0.0625 = 0.3125 lbf.

An ounce-force is the force exerted by gravity on a mass of one avoirdupois ounce under standard gravity, equal to about 0.278 newtons (1/16 of a pound-force). Derived from the ounce in the imperial and US customary systems, the ounce-force is used where small forces are specified in customary units, such as light-duty springs and switches.

Common uses of ounces-force include: Small spring and switch actuation forces; Keyboard and button tactile force specs; Light-duty torque and tension ratings; Consumer electronics component testing.

A pound-force is the force exerted by gravity on a mass of one avoirdupois pound under standard gravity, equal to exactly 4.4482216152605 newtons. The pound-force comes from the imperial and US customary systems, where the pound has historically served as both a unit of mass and of force. It remains standard in US engineering practice.

Common uses of pounds-force include: US mechanical and aerospace engineering; Torque and fastener tension specifications; Rocket and jet engine thrust ratings; Load ratings for hardware and fasteners.

Here are some common values converted:

1 ozf = 0.0625 lbf 5 ozf = 0.3125 lbf 10 ozf = 0.625 lbf 50 ozf = 3.125 lbf 100 ozf = 6.25 lbf
