Pace and watts
Wattbike or BikeErg watts to rower watts and split
Cycling watts are about 1.1 times the RowErg watts at the same effort, so 250 Wattbike watts is an estimated 227 RowErg watts, a 1:55.5 split. This chart converts each cycling watts figure from 100 to 400, in 25-watt steps, and individual variation is large.

- Cycling watts are about 1.1 × RowErg watts at the same effort (Lindenthaler et al. 2018; Wiener et al. 1995).
- The BikeErg split is power-matched to the rower, but equal power is not equal effort (Turner and Rice 2021).
- Similar effort is an estimate: a given power feels different on different machines, so those figures are a starting point and individual variation is large.
Worked example
250 cycling watts is about 227 RowErg watts (250 ÷ 1.1), a 1:55.5 split on the rower. Treat that as a starting point.
How it is worked out
RowErg watts are the cycling watts divided by 1.1. The RowErg 500m split then comes from those watts with the same exact formula used on the RowErg: split = 500 × cube root of (2.80 ÷ watts). The number on a Wattbike or BikeErg is power. The rower figures are the same effort, which is the estimate.
