Convert twip to Earth's polar radius
Please provide values below to convert twip [twip] to Earth's polar radius [R_p], or Convert Earth's polar radius to twip.
1 twip = 2.7748e-12 R_p. To convert twip to Earth's polar radius, multiply the value by 2.7748e-12; to go the other way, divide by it (1 R_p = 360382580546 twip). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 twip = 2.7748e-12 R_p
- 1 R_p = 360382580546 twip
- 10 twip = 2.7748e-11 R_p
- 100 twip = 2.7748e-10 R_p
How to Convert Twip to Earth's Polar Radius
1 twip = 2.77482890122996e-12 R_p

Twip
A twip (twentieth of a point) is a unit of typographical measurement equal to 1/1440 of an inch.
History/Origin
The twip was invented by Microsoft as a device-independent unit for layout calculations in its software.
Current Use
The twip is used internally by some software programs for screen and print layout.
Earth's Polar Radius
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
Frequently Asked Questions
What is 1 twip in Earth's polar radius?
1 twip (twip) = 2.7748e-12 Earth's polar radius (R_p).
How do you convert twip to Earth's polar radius?
